Re: Salt water fish tanks......
snapperbait,First off I wouldn't recommend a tank smaller than say 30 gallons to start.Bigger is better.Most saltwater basic fish tanks once they have gone through the initial nitrogen cycle of around six weeks with break-in specimens require a 10-15% water change every 2 weeks to boost trace elements and remove ever increasing nitrate levels.There are synthetic salt mixes readily available for aquarium keepers.You'll need some basic monitoring tools for the upkeep of your tank to include a hydrometer for montoring specific gravity,a gravel syphon tube for conducting water changes,a suitable plastic bucket for mixing salt water to match the gravity of the tank water,a salt water ph test kit,a nitrite test kit,and a nitrate test kit.Is it getting complicated yet?Not really ,these things will quickly become old hat.Remember that a salt water tank will require substantial water movement through the use of powerheads connected to the lift tubes of the undergravel filter,a properly sized mechanical filter,and the use of either a protien skimmer and or one of the lift tubes driven by air to prevent the buildup of carbonic acid which depletes the ph level below 8.2 and also to add dissolved oxygen to the tank water..8.3 ph is ideal for marine aquaria.Also the subsrtate or gravel of a marine fish tank requires the use of crushed coral or dolomite as it keeps the ph buffered preventing it from becoming too low.These are just a few basics and by no means covers the entire scope of a succesful marine fish tank.Finding a reputable and helpful marine fish retailer will be your next and probably most important search once you have decided to begin a salt water aquarium.Read all you can and avoid enticing specimens that a beginner should not attempt keeping until they have had more experience in the hobby.Here's one good starter book that I use to sell to beginning aquarist that is not too comprehensive nor too basic.It is distributed by Tetra and is titled "Marine Aquarist Manual Comprehensive Edition."Good luck
