I have high phosphates which is causing my tank to have a huge diatom bloom everywhere. Yes the tank is fairly new set up but everything was in a pre existing tank. Im not so worried about the diatom as i have been there and gone through it and with time will go away my bigger concern is I think the cause is high phosphates. I have a 20 gallon sump with a refugium with cheato but it seems that my nitrates and phosphate are staying relativly unstable nitrates bounce from 0 -5- 20-5- 0 through a cycle of two weeks is that common? I have been doing nothing really different in the tank. What type of "phos ban" or similiar product would you recomend putting in my tank?
