I agree with Christy. I read somewhere that it is very difficult to get a proper reading on phosphates unless your tank is algae free. Who has that?
I kind of monitor the algae growth: if it starts to grow faster I change out the Rowaphos and add a little Phosphate Destroyer from Tailored Aquatics. Seems to work for me.
