I have a 60 gal FOWLR tank (for the moment) with Cheato in the refugium of a 20gal sump. I have high phosphates (API reads .5 ppm) but 0 nitrates.
I've read that Chaeto is NO3 limited. Should I dose nitrogen so the Chaeto will grow faster and eat more phosphates?
Or should I just continue to use PhosGuard to lower Phosphates and go from there?
