Heres the story, I started reefing again after a got married three years ago. So I built my own 120g acrylic tank. I didnt finish all the edges but it held water and it worked. it is not as easy as youtube makes it look. so the acrylic 120 in the garage doubled to another glass 120 in my bedroom. i was doing good on maintenance then algea started growing in the acryic 120 and i purposely let it go to see what would happen. Algea wall to wall a year laterand ive only been feeding the single clown in there like once a week and ive been removing 2 gallons of algea every month. So where are all the nutrients coming from. idk. So Im going to build a large display tank in the family room and I broke down the acrylic 120. I pulled all the rock scrubbed it sprayed off and I got it soaking in a saltwater trough until I build the new display tank and fishroom. Have any of you experience with using live rock out of tank after going nuclear algea and putting it in a new tank.???
