Nitrate Dosing

[cliffhanger]

There are some sodium nitrate products available if you don't want to use potassium nitrate. Neither of those will raise phosphate, though.

There is a way without adding any chemical, currently I have a biological load in high fish but I can not raise the nitrate by feeding more without increasing the phosphate

Amino acids won't contain any phosphate, but they do have fixed nitrogen.
