Those dosing NOPX

[Breakthecycle2]

I need a little help from you guys. Can someone give me a definitive answer on how much I should be dosing? Total volume is 250 gallons. Phosphates are .13 per Hanna. Nitrates are 15.

I don't think there is an exact number for the question as each tank is different.
Are the nitrates raising or holding steady?
Is the skimmer producing more by taking out any bacterial flocks?

The skimmer is producing more, yes. Nitrates are on the rise.

Keep adding more per dose slowly till you see it stabilize
With that volume it will be quite a hefty amount
