Making solution for phosphate removal

JMM744 · Nov 8, 2020

Bought a qt of RX Klear phosphate remover and it’s supposed to remove or lower it by 2000ppb in 10000 gallon of water. How much of it would you mix with ro water to dose my system. I am trying to get phosphate down from .32 to around .05 to .1 in a 300 gallon system. I have a dosing pump I could use to dose or by hand.
Math ain’t my skill set!
Thanks so much.

Tbh, even if you did the formula youre still adding phosphates by feeding your tank, alternatively if you feed less you'd also reduce phosphates, or by upping filtration.

But in regards to your Q:
2000ppb/1qt
1qt = 946.353ml
2000ppb/946.353=
2.1133762983 ppb/ml or 0.0021133762983 ppm/ml
So rounding to keep it simple, every ml should reduce by 0.002 ppm.

** double check my math cause I'm just winging the theory using ppb to ppm calculators, and perform the changes slowly.

I missed the dosing part of the question, but like other dosing you'd have to figure out the daily increase and dose based on that

So no need to make a solution, in other words just use straight from container? If I dose 5 ml then it would reduce by .010 ppm?
I appreciate your help.

You need to adjust for aquarium size unless you have a 10000 gallon aquarium.

for instance the whole bottle would reduce 1 gallon of water by 20000ppm.

So you need to get a idea on your tank size. For instance for a 100 gallon tank 1ml would reduce phosphates by 0.2ppm. and 5 ml will reduce by a 1ppm.

What size is your tank?
