I let my 75G go for awhile because of a depressingly overwhelming Caulerpa outbreak. So now that I have that problem taken care of I'm trying to revitalize my tank. So first I found that my nitrates were sky high since the algae was gone. Set up a Sulfer denitrator which reduced my nitrates from 80-100 down to 5ppm now. So now I've moved on to my Phosphates. Using a Fluval PO4 test kit my Phosphates came back at 1ppm. I have an Aquamaxx GFO reactor, but one of the plastic thumb screws is broken. So while I'm trying to get a replacement for that could I dose vodka to lower my phosphates? I do have a Reef Octopus 90 HOB skimmer on the tank which I know is a requirement for dosing. Any thoughts on reducing my Phosphates for a week while I'm getting my reactor back online?
