I have had many tanks and always swore I would learn from my mistakes and do it right one day. I had my last 75g that only had 2 maxi1200's, a HOB aquaC skimmer, and a heater. 4 NO 40w bulbs, and I used dechlorinated tap. Lost a few fish, but had healthy shrooms, gsp, and leathers, never many algae problems. Just brown on glass and rocks and a lil cyano. Always would get stuff that looked cool but caused problems later like a CBS which attacked my fish, blue hermits which killed snails, brittle stars which ate my Banghai cards. Then my house caught fire and blew the tank. This time, beautiful functional stand, hood with 4 VHO and moon lights built in, 15g sump, 15g fuge, more sand, more rock, 3 maxi900's, CSS125, phosban reactor, RO/DI water, and researched animals before they go in. Sand is spotless, water is crystal clear even when it is drained in a bucket, two fish losses, healthy corals, but the worst hair algae Iv ever seen. cut lights down, water changes every week, many "algae eaters", feed every other day, my wife hates the tank because of it and I just want to give up. So frustrating. But, one day, when I find what clears it up, I will have the tank I'v always wanted.
