Aquarium Ideas Sent to Another Country in 1997 Adrian R. Lawler, Ph.D. In 1997 the author was asked to present a brief summary of items to consider in building an aquarium in another country. The ideas were sent via email; various plans and documents were copied by a visiting scientist for transport to the country. Extraneous comments, country name, and dialogue were deleted in the presentation below, leaving just the comments on aquarium, which were then organized better. ORIGINAL SMALL AQUARIUM Other rooms were: (1) small lecture/movie room, (2) small kitchen/projection room, (3) two small bathrooms, (4) office, and (5) two small labs/lecture rooms. This facility was used until we opened the larger aquarium in 1984, and was mostly visited by school groups. AQUARIUM CONSTRUCTION Our exhibits of living animals are based on the water cycle. Water falls on land, flows through fresh water (FW) streams, to estuarine areas, to Bay/Sound, past barrier islands, to the Gulf of Mexico. Your exhibits could be based on monsoons, etc. with the different habitat types you want from jungles/hills down to coast and sea. You should decide this. You could do: FW streams, rivers/lakes, estuarine area, sea, coral reefs, etc. Displays depend on what animals you want to exhibit. You can have vivarium tanks (part land/part stream) to full water tanks. One popular display is touch tanks, where non toxic, non pinching/biting animals are put so the public can pick them up to examine them. These animals also have to be hardy to withstand handling stress. You should have either UV or ozone sterilizing units on the system, or both, so visitors do not get infected with various aquatic diseases. Our lobby displays are various interesting/rare fish in tanks, preserved specimens, shell collections, fossils, nets hung from ceiling, types of oceanographic data collection gear, video stations, local marine art, information on local fisheries, educational leaflets, local happenings, etc. I know nothing about construction costs in your country. You suggested we use our aquarium as an example, so: built in l983 at cost of 3.5 million for 33,000 square feet....or about $106 per square foot. This would now cost l2-l5 million...or $364 to $454 per square foot. This includes a 313 seat auditorium, lobby, gift shop, library, l2 offices, 6 bathrooms, photo room, print room, shop, kitchen, 7 classrooms/labs, storage rooms, and the original 27 display tanks. We have about a 7-acre site for this aquarium with a lot of parking but no native plant display area outside. Copies of the plans of the Aquarium in Biloxi are going to be delivered to you. Good clay was brought in and packed to raise the building above storm surges. Pilings were driven to support the weight of tanks and the major support columns of building, and piling caps of concrete were poured. All tank drain piping to sumps was laid in clay (making sure clay under pipe was well packed so pipe did not bend and crack), and the tanks were poured with concrete. All plumbing/wiring was verified correct and then the floor and sumps were poured. Then support columns for building were poured, and it was blocked in between support columns to make room divisions. We have about 75 pilings under this building, 50 being under the aquarium area supporting the tanks. Pilings should go down to solid footing. Here they now drive/vibrate hollow steel pilings down to about any level they want, weld on more sections as they go, then send high pressure water down pipe to drive dirt out, and then fill the hollow pipe with concrete. This procedure is EXPENSIVE, but these type pilings are stronger than driven wood pilings and fewer would be needed. On any Aquarium the first concern is location, location, location: In building an aquarium you usually put in the large tanks first, then build the building around these tanks. Smaller tanks can be added later. I would have the building front designed to represent something that the public can easily recognize from their culture, e.g., a favorite fish, etc., etc. Tank comments We use all-glass aquaria up to the 210 gallon size. The cost for tank alone is $1-2 per gallon. These tanks are in a small tank display area, plus in isolated small tank displays in various parts of the building. Fiberglass 210 gallon display tanks, with tempered glass front and back, cost about $3000 each. A mold is made of design wanted, then tanks are made off this mold; fiberglass tanks like these cost about $15 per gallon. We have l9 of these in a clover-leaf design around a central circular main tank. We have 7 medium size tanks (l200-4000 gallons) that are in the corners of the alcoves formed by the l9 fiberglass tanks. These tanks are concrete with acrylic viewing windows and with tempered glass covers so acrylic tank window does not get scratched. I would estimate 1997 cost at $15-20 per gallon. The circular main tank is made of concrete and has 14 acrylic viewing windows, holds 42,000 gallons, and would cost from $800,000 to $1 million. Other tank costs: 500 gal circular acrylic tank, with stand, light hood...$l8,000 This aquarium originally had 27 display tanks. We did later construction and moved things around to add 21 more tanks. Some were small tanks (10-30 gallon) in a wall 3 tanks high. These tanks are used to quickly display animals of local or seasonal interest, fish with various diseases (lymphocystis; isopods; leeches; etc), dangerous marine organisms, those used in aquaculture, etc. In addition to display tanks, you will need back up tanks behind the scenes for holding, treatment, quarantine, rearing, etc. We have about l00, varying in size from 10 to 1000 gallons. Smaller tanks are all-glass and cost $1-2 per gallon. Larger tanks are fiberglass (no windows) and cost about $2 per gallon. Filters, pumps, plumbing, air lines, light fixtures, etc., are extra costs. If you are making your own salt water you will need mixing tanks behind the scenes. We have two (each about 9500 gallons), one for mixing up/aging/treating salt water; the other for holding fresh water and treating it for chlorine, ammonia, etc. These tanks are concrete, interconnected to each other and to two mixing/transfer pumps (5 hp...about $800-$1000 each) so we can mix, use either pump, and send water to any tank in building. All display and back-up tanks are separate units; water does not flow from one tank to the next. So we can vary temperature and salinity per tank, plus isolate any disease outbreak. If you use flow through water, tank designs will be different. AQUARIUM SUPPORT Emergency power: There is an alarm system on the generator to warn us of low battery charge (that would prevent generator starting), etc. Air PVC pipe plus labor to hook up for air lines will be in the thousands of dollars. Have shut-off valves at various points in lines so can shut off air to 1 or more tanks but rest will still have air. Also have shut off valves to control air to each tank. Air intake (here) is through a vented hole in machine room wall on second floor; this is not the best idea. Air system should draw non-polluted air (ours faces a public marina and boat fumes are drawn into tanks = bad). You might want to put an air filtering (activated carbon) unit prior to blower intake. Alarms Cover any pull alarms in public areas so people won't set them off as pranks (mostly done by children). Electricity You want to wire in enough electrical panels and enough outlets to handle expansion. You'll probably need 5000-l0,000 AMP service, 3-phase. All wiring should be in PVC conduits, boxes, switches, etc., to retard salt corrosion. Outlets around tanks should be on ground-fault interrupters for safety. Outlets should be above tanks to prevent water getting into boxes. Keep lighting on separate circuits from outlets for electrical support equipment (pumps, filters because if you put lighting on automatic timers at the breaker panel you do not want to turn anything else off). Breakers in panels should be minimum of 20 AMPS for each circuit; I prefer 30 AMPS per circuit so you can put two sand filters on the same circuit. Our tanks from 210 gallons on up have 3 outlets above each tank, the 2 outside are for tank lights and are connected to a timer that can be set for automatic light on-off control. The middle outlet (a separate circuit) is live 24 hours per day, and is used to run pumps/filters or other things that have to run all the time (UV sterilizers, etc). We have 4 main panels that run all items for aquarium: We are constantly adding more outlets as we get more money for pumps, filters, new tanks, etc. Electricity for whole building will run into hundreds of thousands...depending on what you do. Plumbing Flow-through SW supply If you use a flow-through system, the intake should not be near surface (to avoid intake of floating oils, pollution, FW flows) and not near bottom (to avoid intake of sediments and toxins that concentrate in sediments). Water Water pipes should be PVC as much as possible to avoid heavy metal toxicity. Should have FW + SW going to each tank. Install several shut-off valves so can isolate and work on various parts of the water system. Cost of water system will be in thousands. May add filters to incoming water (added cost) to clarify and detoxify water. Would be good to have your own private FW, and maybe even SW, well. Drains The large tank and both mix-tanks have overflow pipes which also drain to these sumps. Cut PVC overflow pipe at highest level you want water to be in tanks, and screen overflows to prevent animals, etc from going down overflow pipes. All 5 sumps drain to a manhole outside building with an about l0-12" PVC pipe in the bottom, which (in our case) runs about 200 yards to dump into our local BAY. Our waste waters are not treated in any way; this could be better, as medications, chemicals, etc., used in our operation also go down the drain. Your idea of using this water in an artificial marsh/wetland area outside the building for an added attraction would be excellent. You could make a raised walk nature trail in this area. Lighting - 2l0 gal tanks: Original set-up was two outdoor flood light fixtures (that swivel), one above each end of tank. Can direct light; used l50 w flood light bulbs, clear, blue, green, red, yellow. Different colors used (trial and error) to see which would be best for LESS algal growth. Found BLUE in our case to work best. Lights are about 2 feet above the water in tank. - Medium-sized tanks: Tanks have combinations of flood lights (l50 w) and cool-white (usually). Each tank with 1-2, 2-unit fluorescent fixtures above water (2-3 feet) attached to angle iron grid-work that juts out over tank. This grid must be strong enough to support weight of lights PLUS someone leaning out to change bulbs. Some tanks with added l50 w flood lights. We changed lighting so that we got less algae to grow and thus had less work cleaning the viewing windows. - Large tank: It has a large grid system about 8 feet above water that is both suspended from ceiling with rods and supported by resting on safety railing around walk around top of main tank. This tank has 4, 250w metal halide lights, about 50, 150w flood lights, and several fluorescent lights. It's a mixture that NO lighting engineer has inspected or given approval to. It works. - Night light: All medium/large tanks have small fluorescent lights that are on all the time. This is so when lights go out there is a little light left which simulates moonlight for the fish, and does not give a sudden change from lighting to darkness (which can frighten some fish). Lights on 210, medium, and large tanks are all connected to timer that turns lights on at 7:30 am and off at about 5 pm. So have about 9.5 hrs of light per day. - Misc. display lights: For reptiles in vivarium, and various snake enclosures, etc. we have various lights with a high CRI (color rendering index) to simulate natural sunlight so animals get some vitamin D. Use lights of CRI of 95 or higher (l00 = sunlight). Our systems work...but I'm sure a lighting engineer could improve them. For working lights in area behind aquarium we have 4 foot fluorescent fixtures plus 8 large 250 w metal halide fixtures on ceiling. In times of power failure we have battery-powered lights over each tank that automatically come on when power goes off. These give enough light so patrons can still see into tanks. In the viewing area, light is primarily supplied via tank lights. The walls, etc are black so that the tanks stand out. We have lights in the ceiling on dimmer switches to control amount of extra light we want. When handicapped people from local hospitals come in we can turn up lights so they can see better to navigate while viewing tanks. - Rest of Building: Lobby = metal halide lights. Offices, library, halls, other areas = 4 foot fluorescent fixtures, cool white. Auditorium = flood light fixtures on dimmer switch. Outside = flood or mercury vapor lights. GRAPHIC PANELS These panels match walls = plywood covered with black Formica. with light fixture. They can be made for about $100-200 each. For larger tanks we have 3-8 such panels. For vivarium and small tank display, the panels are over the tanks. For quick graphics you can scan pictures onto white paper, and cut to fit panel. These work ok for temporary graphics. Permanent graphics are cibachrome prints that cost about $50-75 each. MIX-PUMPS/other pumps: Mix tanks are concrete, bottom sloped to drain, overflow pipe going to sumps, city water plumbed to top of tanks. Square manhole in top middle with wooden cover to: prevent people falling into, keep trash out of water, keep light out of tanks (decrease algal growth). Mix pumps lower than tank bottom...pump from bottom. Pumps in a sump with a DRAIN to outside so if pipes leak sump not filled and ruin pump motors. These mix pumps run about $800-1000 each. Breaker panels nearby so can be thrown quickly in emergencies. Water aerated by pumps to blow off chlorine from city water; AmQuel added to neutralize ammonia in water. (can also use zeolites for ammonia removal in FW...prior to adding salt). Can also put charcoal filter in line prior to mix tank. Costs: Big sand filters and pumps = $l400 each, DE filters and pumps = $700 each. Exhibits in aquarium viewing area (in addition to graphics): Living exhibits in aquarium: We are mandated to display organisms native to Mississippi and the adjacent Gulf of Mexico. We also try to emphasize organisms used in aquaculture (FW & SW) in our state, various diseased fish to inform public; various unusual things; fishes of sport fish interest; fishes used in toxicity testing of our local streams; organisms researched by our staff with verbiage explaining the research; commercially important invertebrates (crabs, shrimp, oysters, etc); things of seasonal interest; organisms constricted by plastic litter; other things of interest. Aquascaping the tanks: We add local plants, logs, shells, bottles, nets, etc. to decorate tanks. Vivarium: waterproof box with double paned viewing window. expandable foam (polyurethane) contoured to form banks of stream, covered with fiberglass, last layer of gel mixed with sand so it looks like a sand beach; water flows between bank and window so public can look through window to see animals underwater. Back wall is a mural showing progression from wetland to Cyprus swamp. One corner has Cyprus knees + hanging Spanish moss...to match Cyprus in mural. Sand put into stream so turtles can bury up. Lighting with high CRI for turtles. FW 210's: pea gravel as substrate; logs; native FW plants. Back glass painted a sandy color. One tank set up as a small vivarium; this is where we put baby alligators and baby turtles. Stream (water area) against tank window at front. Lexan top on all 210's to decrease evaporation, decrease spray, prevent animals from jumping out, prevent foreign objects/dust from entering tanks, etc. Each lexan cover costs about $75. Aquascaping: Medium/large tanks. We use fake rocks made out of fiberglass; PVC pipe burned with a blowtorch to make it look like a log or piling; real rocks; fiberglass boats/boat parts; trawl boards with iron foot removed and all bolts replaced with stainless steel bolts; glass floats; fake anchors made out of PVC pipe; tufa rock mortared together to look like a coral reef; logs, some of which are hollowed out and filled with concrete so they sink; dead coral; deal sea fans; shells; concrete caves; live plants; bottles, other debris found on our local beaches, etc. We also use plastic grass/plants in various tanks; this is ripped up and ingested by sea turtles and torn up by triggerfish. COLOR of tank walls: each alcove has tanks painted inside with a different color epoxy-type non-toxic paint. FW= sandy color; offshore tanks = blue, etc. LOBBY EXHIBITS: (live potted plants all around) Exhibits going up ramp to auditorium: Above, plus what previously sent, are our main exhibits. In halls, library...various posters on sea life, whales, sea turtles, snakes, stuffed animals, etc. AUDITORIUM: videos on sea life, etc. run continuously. Each clip is about l5 minutes with tape lasting about 2 hrs; automatic rewind on tape so a human worker is not needed in the auditorium all day, just to start and stop the video. Our new video projector cost $14,000. Auditorium also has posters, murals on walls. Space Utilization Remaining 37% of building is included in bathrooms, halls, offices, print room, photo room, janitor's closets, storage, stairwells, elevator, machine room, electrical power room, shop, kitchen, video room, etc. If I were to redesign this building I would allow more space for gift shop, classrooms, back-up tanks behind scenes, library, storage, and lobby (so could get in more displays). For your Aquarium I would also include space for a restaurant/snack area for the patrons, plus an outside area with picnic tables in a natural display-type setting. Our space could be better utilized by having educators stationed in classrooms (that would also be their office), thus freeing up office space they now utilize. Could have a small area in each classroom sectioned off so it could be secured. Classroom would then serve as office, lab, and a classroom. I would also allow more fridge/freezer storage space. Need freezer space to store at least 1000 lbs. of frozen fish/squid/shrimp for aquarium food. My new 3-door upright freezer that can hold about 1500 lbs. cost $4800. Facility problems you should avoid Project development/funding ...Contact an aquarium organization which has recently gone through the
planning/design/fundraising steps to get ideas of things you should consider. ...Some other fundraising ideas: Grant information ---A strong mission statement/aquarium theme. Other items as deemed important for proposal. Approach potential funding sources to make sure your application will be suitable, and verify they might be interested in funding such a project. Also, you can detail how computers and programs will assist/run various things in facility, from lights on/off to water flow to tanks to gift shop, and HOW these things will be innovative and futuristic so as to showcase the facility and the granting agency. Detail also the innovative projects in aquaculture, sewerage treatment, water purification, water re-use, plant cultivation, etc., etc., that will be done using computers/software to showcase the future. After above is done then one can have a strong proposal for a granting agency. Good luck to all! |
