raising NO3 without PO4, cant add fish

[needlehandssoftfingers]

ive seen ammonium chloride, and potassium nitrate.
which will only raise nitrates?
i cant add more fish currently, and id love some formulas if possible

Amino acids are the perfect option. Tasty nitrogen as they call it

Sodium Nitrate is what you want. You can get it on Amazon. I dose it when my phosphates outpace my nitrates for various reasons.

To add more confusion-Randy likes Calcium Nitrate and that's what I started using. Sodium Nitrate is OK, but I would not recommend Potassium Nitrate as you are not testing potassium in your tank, so you don't know when it accumulates.
