I have a 55gal tank. It has been set up for about 7 or eight weeks. I have an anenome, maroon clown, a neon damsel, a sally blue crab, and 6 snails. I have two millenium 3000 hang-on filters and a sea clone 100 protein skimmer. I started the tank with tap water, my first mistake, I have done a 30% water change already. My tank bottom, rocks, barnacles, shell, and plants. Is it a problem or should I just let it go. I will be taking my tank down some time between now and July, we are moving, and am planning on over hauling my tank and converting to a sump/refugium filter system. Should I just let it go and just start over with RO/DI water and recycle my tank when I set it back up. Also, I would appreciate any advise on what type of sump system to set up. I would like to build my own and have a few ideas. :o
