i got my marine nano about a month back from my dad who wasn't looking after it properly for months until i convinced him to hand it over. The tank was a wreck, all the levels were wrong, algae and cyno had taken over the place, i've managed to get it back to a decent state with only phosphate and ph to fix. Just three days ago i bought a torch coral for my tank, and for the past two days it has started to wilt. Could a difference in the ph levels caused this. I've got the tank well lit so i dont think lightings an issue and all but my phosphate and ph levels are good.
