Given that... it says 1mL of the solution doses "0.53 ppm of PO4 in 10 gallons of water". I have a 40 gallon tank. and my Nitrates showed between 80-100. Does that mean i need to get 10ppm phosphates in the water? that's a lot of dosing? no?
I would first try to lower those nitrate levels (to say 20 ppm or lower, preferably) before dosing your phosphates.
