My cheato dosent really grow that much.I have good flow through the fuge have a pice of rock and that clamp on light jbj macro grow on 24hrs most of the time mabe everyother day I shut it for a few hrs because I have a clown fish in there. I know its not because I have no phos I usually get .05-.02 on the hanna and have some algae here and there.IM just wondering because I hear people trimming it down a lot.Could it be the light is not strong enough?
