I have this gha that came on the live rock I recieved, I thought for sure my cycle would kill it while cycling, but it hasn't, and now I have this problem, phosphate and nitrate are at 0 , tank is 3 months old, 40g breeder, I have 2 clowns in sump, one in display, a 6line wrasse, a a watchman goby, an emerald crab, a conch, 20 ceriths snails , 20 astrea snails, 13 hermits. I haven't done a water change since may28 , cut the skimmer off first week of June because I had dinos, however I found this crap is my issue, how can I resolve it in an already ultra low nutrient system??? Most things I'm finding are saying to lower nutrients, but mine are 0 bc this is sucking it all out
