[Creetin]

I would like to know what you strive for in po4. Mine is at 0.03, Would like 0.02 but I am having some cotton candy algae die off in my fuge and is impossible to do at the moment, but once that's over I don't think that's a problem because I achieved it before.
Curious if I should lower my numbers, I know zeo users like it to read 0.00
Also what do you use to achieve it?
I dose vodka 10Ml every other day, run GFO, Run phosguard in my ca/rx effluent, and have a fuge full of chaeto.
