I’ve had this scoly for over two months. And I’ve the time it just recessed then two days ago it was gone. Lost one hammer and my acans are receding too…… my other hammers and torches and gonis are all fine. Water prams; NO2-0 NO3-5-10 PO4-.06 temp is 77.5-78 salinity is 1.24 I don’t have calc or mag but what could cause this??? I’m stumped
