Just a quick parameter check, just asking for opinions,
this is for a mixed reef 40 gal breeder.
phos - 1.5 = salifert
nitrate - .25 = salifert
mag - 1410 = salifert
alk - 7.7 = salifert
cal - 401 = hanna
I cleaned the glass twice a week, there`s no algae on the sand nor on the rocks, this tank is also sumpless.
