I have come to the conclusion that I think my two year battle with what is either gha or turf algae is because of leaching phosphates from the rocks. When I started the tank I used brand new macro rock and I have heard that it can leach phosphates that lead to algae. I have no algae anywhere but the rocks and zero phosphates in the water column. If I were to take out these rocks and replace them with dry or wet live rock could this be a solution where the algae would not return?
