A 30 g allon a q uarium with 25 g allons of sea water, crushed coral, decorations and other e q ui p ment will wei g h about 240 p ounds. That is wh y once y ou fill it, the a q uarium should be considered a p ermanent fixture. The settin g in which y ou p lace y our a q uarium is also ver y im p ortant. The health of y our animals de p ends a lot on how much li g ht and heat the a q uarium receives. The tank should be p laced on a level structure awa y from direct drafts and sunli g ht. Drafts p roduce ra p id dro p s or rises in tem p erature. This will cause stress and a lowerin g of resistance to disease amon g y our animals. Ex p osure to direct sunli g ht can often cause an undesirable g rowth of al g ae and a p ossible unwanted tem p erature rise. Fish are cold blooded. Their bod y tem p erature chan g es with that of their environment. Extreme chan g es often lead to stress, diseases and death. The a q uarium should be p laced in a well-traveled area. This will allow y our fish to become accustomed to outside movements and will make them easier to observe.Artificial Sea Water or Natural Sea WaterSea water for the a q uarium ma y be either s y nthetic or natural. Local marine life can survive q uite well in water from the collection area. Althou g h this water ma y be dark colored or contain sus p ended matter, most of this can be removed b y p ro p er filtration. If exoticArtificial Sea WaterArtificial sea water is made b y addin g p re p acka g ed ocean salts to ta p water. Before the p re p acka g ed salts are added to ta p water, thou g h, the chlorine should be taken out of the ta p water. In order to g et rid of chlorine in ta p water allow the water to stand in p lastic buckets for at least two da y s. To mix the salts and water sim p l y follow the instructions on the p acka g e. Once the artificial sea water is in y our a q uarium wait at least two weeks before addin g fish or other animals. This two week p eriod will allow the sea water to stabilize and become more suitable for the animals. Remember, the p ro p er p re p aration and care of the a q uarium means life or death to the fish.Natural Sea WaterIf y ou live near the ocean y ou can collect the water to fill y our a q uarium. Unless y ou collect the sea water far out at sea y ou will be g ettin g contaminants with the water. Sea water near shore is usuall y p olluted with various chemicals and metals that react with the salts in the sea water. These chemicals and metals come from streets, y ards, farm lands and industrial com p lexes, and are washed into the rivers b y rain and carried to the ocean. When collected near shore, sea water will have contaminants to some de g ree. Fish that live in the water

Collectin g because some will be lost in the cleanin g p rocess. durin g this time will lessen the chance of g ettin g contaminants in the water. Collect the water in containers made of g lass, p lastic, or some other non-corrosive material. When y ou g et the sea water home, filter it throu g h a funnel containin g dacron floss. Store the filtered water in a container with the cover on. Allow the water to sta y undisturbed, for at least two weeks. The water should not receive an y li g ht or air durin g the two week stora g e p eriod. This stora g e p eriod will kill most of the microor g anisms and al g ae in the sea water. You want the sea water as p ure as p ossible before p uttin g it in y our a q uarium. Durin g this p eriod of stora g e y ou can be p re p arin g the bottom materials which will g o into the a q uarium.Bottom MaterialA g ood material to use in the bottom of a marine a q uarium would be co q uina shells (Donax "Perwinkles"), calcified al g ae, dolomite or crushed coral. Do not use colored rocks or sand in a marine a q uarium because the y ma y contain p reservatives that could be toxic to y our marine animals. Small shells and other p ieces of limestone material hel p to kee p the p H of the sea water toward the alkaline side (non acidic). If y ou collect y our own material from the beach remember, don't use an y container, sifter, shovel, etc. that is made out of metal. Use onl y non-corrosive containers and e q ui p ment. Collect or bu y enou g h bottom material so that it will make a la y er that is at least two inches thick in the bottom of the a q uarium. The number of g allons of bottom material that y ou will need is eas y to calculate. will need at least 3.75 g allons of bottom material. ToCleanin g It is best to clean the bottom material outside, in the y ard, so y ou don't make a mess in the house. Pour p art of the collected material into a p lastic bucket so that it fills the bucket no more than 1/3 full. Clean the material b y flushin g the bucket of material with fresh water from a g arden hose. As the water fills the bucket, stir it with a stick. Don't stir it with y our hands because there ma y be shar p ob j ects (sea urchin s p ines, p ieces of broken g lass, etc.) that could p oke or cut y our skin. As y our stir the flushed bottom material, dirt and or g anic debris will float to the to p and flow over the ed g e of the bucket with the water. This is p art of the cleanin g p rocess. When the water is clear, drain the water out of the bucket and scatter the bottom material out over a flat surface such as a table to p p atio or the g round covered with a p lastic sheet. Wash the remainin g bottom material in this manner. Allow the bottom
Startin g and Maintainin g A Marine Aquarium Pa g e 6July 1981material to remain out in the sun for at least one week. Bottom material should be scattered where nothin g will disturb it. While the bottom material is dr y in g y ou can be g in to set u p the a q uarium.Settin g up the AquariumFiltersThere are two different kinds of filters with which y ou will need to su pp l y y our a q uarium. One kind of filter is the subsand or underg ravel filter. The other t yp e is the outside p ower filter.Subsand FilterThe subsand filter slowl y moves the water in the a q uarium throu g h the bottom material (shells, co q uina, etc.) and back into the a q uarium. This is a ver y im p ortant filter to have because it removes or g anic waste matter. Bacteria which lives in the bottom material will take waste matter that has been p roduced b y the animals, and convert it into harmless matter. If y ou have the t yp e of subsand filter that uses an air p um p as shown on p a g e 6, the air p um p should be p laced hi g her than the water level in the tank. If the p um p is below water level, salt water ma y travel down the p lastic tubin g to the p um p If the electricit y g oes off, water will back u p into the p um p A q uariums have also been known to si p hon themselves onto the floor after the p lastic tubin g had worked loose from the vibratin g p um p Oh what a mess that is! Keep the pump above water level! Some subsand filters work b y usin g a water p um p with im p ellar blades rather than an air p um p to move the water. With this t yp e of p um p there is no dan g er of the a q uarium si p honin g itself.Power FilterThe outside p ower filter removes sus p ended matter, toxic g ases and water discoloration. It also p rovides ver y g ood circulation of water which is beneficial in marine a q uariums. This t yp e of filter is p laced on he outside of the tank and is driven b y a motor. The water in the a q uarium is si p honed, via si p hon tubes, into the filter box and moves down throu g h a la y er of carbon and filter floss. The carbon absorbs waste matter such as ammonia, urea and carbon dioxide. Make sure y ou use carbon and not charcoal. Carbon lasts much lon g er and is a better filterin g material. The bottom la y er of filter floss will p ick u p p articles missed b y the u pp er la y er of carbon. In order for the si p hon tube to work it is necessar y to kee p the water level in the a q uarium at least 1 inches from the to p After the water moves throu g h the carbon and filter floss it is then p um p ed into the a q uarium via the exhaust tube. Kee p the exhaust tube above the level of the water so that it will hel p aerate the water.
Startin g and Maintainin g A Marine Aquarium Pa g e 7July 1981Fre q uent cleanin g of the p ower filter is not recommended unless the filter is so clo gg ed that circulation is slowed down. Cleanin g will interru p t the im p ortant denitrif y in g action that takes p lace in the carbon and floss. This t yp e of filter should rarel y re q uire cleanin g more than once a month. (Hallett) Remember to kee p the filters on the ends of the si p hon tubes clean. Also make sure that these filters are secure and won't fall off. Small animals can become tra pp ed in the si p hon tubes or sucked into the p ower filter if the si p hon filters are not on. Read the directions to the p ower filter carefully Pro p er construction and maintenance (oilin g chan g in g floss, carbon, etc.) is ver y im p ortant to its functionin g p ro p erl y .DecorationsIf y ou use rocks to decorate the inside of y our a q uarium, choose rocks that are not p orous. Porous rocks have small holes that will collect or g anic matter and allow small animals to hide. The small animals that hide in the s p aces will eventuall y die and p ollute the a q uarium. Make sure that the rocks y ou use either have no small holes or that the holes are lar g e enou g h so that small animals cannot hide and can be removed easil y if the y die. Coral is p robabl y the most fre q uentl y used decoration for marine a q uariums. It is ver y natural and its chemical q ualit y is conducive to g ood sea water conditions.

After soakin g in fresh water, smell the material. It should be free of an y trace of bleach before addin g to the a q uarium. Soak sea shells in a bleach solution for onl y an hour to kee p from ruinin g the nice outside luster of the shell. It is ille g al to collect an y t yp e of coral in Florida. If y ou would like to use coral as a decor, check with an a q uarium sho p or one of the man y shell sho p s throu g hout southern Florida.Li g htin g It is necessar y to cover the a q uarium if y ou use a li g ht. Fluorescent bulbs are the best for marine a q uariums. Fluorescent li g ht shows the animal's colors to the maximum and hel p s to p romote g reen al g ae g rowth which is hi g hl y desirable.

Time and the method used in introducin g the animals to their new home are the most im p ortant factors in successful a q uarium kee p in g Follow the su gg ested p rocedures below and y ou should have 100 p ercent success: 1.Turn off the a q uarium li g hts and dim the room li g hts. 2.Take the water tem p erature of the water, both in the a q uarium and in the ba g s. 3.Float the ba g (containin g the animal) in the a q uarium and p lace an air stone connected b y tubin g to an air p um p in the ba g 4.Pour about one half cu p of the a q uarium water into the p lastic ba g Do this ever y fifteen minutes until the tem p erature of the a q uarium water and the water in the ba g are e q ual. 5.Once the two tem p eratures are e q ual allow the animal to remain in the p lastic ba g for another half hour. Don't get impatient! 6.Do not ti p the ba g and let the animal swim out into the a q uarium. This will cause the animal's waste p roducts (ammonia, urea, nitrates, etc.) which have accumulated in the ba g to g o into the tank. 7.Pour the water from the ba g with the animal, throu g h an a q uarium di p -net over a sink. Immediatel y but carefull y p lace the di p -net with the animal into the a q uarium and allow the animal to swim freel y out of the net.
Startin g and Maintainin g A Marine Aquarium Pa g e 13July 1981The aquarium water should have a clean smell and be crystal clear. If the water is not clear and you can smell an odor, the water is bad.8.Kee p the li g hts dimmed for the rest of the da y Do not feed for 24 hours. After 24 hours feed onl y li g htl y .Feedin g How often and what y ou feed y our a q uarium animals is extremel y im p ortant. Fish should be fed twice a da y but in small amounts. Food that is not eaten should be taken out before it be g ins to deca y The more y ou can var y the diet, the healthier y our animals will be. You would even become tired of sirloin steak ever y da y After a while y ou should be g in to learn what kind and how much food y our marine animals will eat. Some a q uarium animals will p refer certain foods and re q uire different amounts than some of the other animals. The animals that move around a lot will p robabl y re q uire feedin g as much as twice a da y while those that p refer to remain q uiet will be able to g o for several da y s between meals. Some excellent foods, which are available freeze-dried are: brine shrim p mos q uito larvae, tubifex worms and ocean p lankton. Live brine shrim p are excellent to feed to most active fish as well as to molluscs (scallo p s, clams, etc.) and livin g corals. Include al g ae in the feedin g p ro g ram at least three times a week. Al g ae hel p s to maintain the bri g ht colors of the an g elfish, tan g s, and p arrot fishes. Dried flake food should not be used to start y our a q uarium. Flake food should onl y be fed to the animals once the y have g otten used to their new environment. Use flake food s p arin g l y Once or twice a week is enou g h. Learn what kinds of foods y our animals eat in the wild and feed them those kinds. Remember, don't over-feed y our animals!Water MaintenanceOnce the a q uarium is set u p with water, e q ui p ment and animals it is necessar y to maintain it in g ood condition. Animals p roduce toxic wastes and the wastes will continue to increase as time g oes b y An a q uarium is a closed s y stem. There is no natural chan g in g of sea water. Even with filtration, toxic levels can build u p unless the necessar y measures are taken. One of the most im p ortant thin g s is to re p lace about one fourth of the water in the a q uarium with fresh seawater. How do y ou know when the water needs to be chan g ed? Look at its color. Is it the same color as it was the first da y ? Smell the water. Does it have an odor? It should not have an un p leasant odor. If the water is not clean and has a smell, it should be chan g ed. Sim p l y si p hon one fourth of the water out of the a q uarium and discard it. Slowl y add new seawater. Alwa y s kee p an extra su pp l y of seawater hand y in p lastic buckets. Even with a to p on the a q uarium, water will eva p orate from the a q uarium. It is im p ortant to remember that salts will not eva p orate with the water.
Startin g and Maintainin g A Marine Aquarium Pa g e 14July 1981Re p lace an y water that has been lost due to eva p orationit is su gg ested that y ou select one or more of the books with either distilled water or a g ed ta p water. Do not and p am p hlets on the reference list. take water directl y from a faucet to fill the a q uarium. Fresh ta p water contains chlorine and this mi g ht kill the animals. Ta p water should be a g ed in a p lastic bucket for at least a week in order to g et rid of the chlorine. To kee p track of eva p orated water p lace a p iece of ta p e or a mark at the be g innin g water level. As water eva p orates the level will g o down. Re p lace the water slowl y so that the newl y added water will not shock the animals. Before addin g the water check its tem p erature. The water to be added should have the same tem p erature as that in the a q uarium.Potential ProblemsThe p roblems listed below are two of the most common p roblems associated with kee p in g a salt water a q uarium: 1.White s p ots on the fins and bod y of fishes. The white s p ots are tin y p arasites known as "oodinium". The infected fish will usuall y "breathe" ra p idl y and scratch themselves on rocks and other ob j ects. The infected fish should be p laced in a se p arate "hos p ital" or treatment tank containin g one teas p oon of 1 p ercent co pp er sulfate solution to one g allon of seawater. Leave the fish in this tank for about one week. Do not attem p t to treat the fish in y our main a q uarium. Make sure that the treatment tank has g ood water, p lent y of aeration and filtration. 2.Ver y small, white, bu g -like critters that a pp ear on the g lass of the a q uarium. These co p e p ods are about as lon g as the wire of a p a p er cli p is wide. The y are not harmful to marine fish but usuall y a pp ear j ust before the water in the a q uarium becomes p olluted. lf y ou feed y our marine animals too much, some of the food p articles that are not eaten will be g in to decom p ose. These decom p osin g food p articles will be g in to foul the a q uarium. When this ha pp ens, the little white co p e p ods a pp ear. When y ou see these co p e p ods, y ou should chan g e the water immediatel y Chan g e at least the water volume with either artificial sea water or natural sea water that has been p ro p erl y filtered. There are other p roblems which ma y occur. For descri p tions of other fish diseases and their treatment,REFERENCESBooksAquarium Fishes in Color J. M.
