Where does everyone keep try to keep there phosphate levels at? i know 0 is the goal but within reason. i just measured my levels with a hanna phosphate checker and it showed 0.08 is it time to start running GFO again
Phosphate should never be 0. You need some phosphates. In the range of .04-.06 is good.
whats the best cheapest gfo
