Yes actually, I did! I put the zoa rock back in there I quickly realized it would be a mistake to ever put anything from here into the big tank because of the blue clove polyps. Don't want those spreading to my 90gal! Besides, this tank looks so much better with it in there. I have continued weekly almost 100% water changes along with turning the light up. Things are looking better. We'll see. I might just swap out some of the coral for more of the types that are doing well in there.
