I notice that a lot of people in here have fish aquariums at home. I also have a 55 gallon tank that I had 5 piranhas in for a long time. Due to a recent move I decided to give them away instead of keeping them. Now I am settled down and would like to set this tank back up. In my mind I am considering going for a salt water tank. I have seen some tanks and I think that the ability to keep things like clams and sea horses along with some brilliantly colored fish is appealing to me. My only problem is that I have no clue on doing a salt water tank. I know that they are much more work, but I think I am ready to try. My question, can anyone give me a rough estimate of what I will need. How to set this up right. I will take any advice or comments on what you guys think of this. I am sure someone has a saltwater setup or has tried at some time. I have a 55 gallon tank with a large canister filter. Thanks guys.
