Loudwolf nitrate

[saltgogi]

Which nitrate product do you guys use from loudwolf?
I use sodium phosphate monobasic and was wondering which one for nitrate.
There isn't a sodium nitrate but there is a potassium nitrate. Would this be the best choice?
Theres also calcium nitrate and magnesium nitrate but i'm assuming these also raise calcium and magnesium and I don't want to do that.

Thanks for the help!

That's odd... I've used Loudwolf Sodium Nitrate previously and didn't have trouble finding it. I haven't ordered it in awhile, though. I think I ordered it through Etsy.

I've heard of others using Potassium Nitrate.

I think they used to have them but not anymore.


This is what I ordered. Gonna be a pain to dissolve because they are granules but i think it's pure enough to do the job.

I'm not a fan of using potassium nitrate unless you are monitoring potassium.

This is another option for sodium nitrate:

Could someone double check my math? I used the same formula i did for when I figured out how much phosphate to add. Except switched the value i want to raise the tank by according to nitrate instead of phosphate.

I have approximately 40 gallons of water which equals about 151 liters and would like to raise the nitrate by 0.125 ppm per mL of solution.
So it would be:
151 * 0.125 = 18.875 mg.

So 1 gallon = 3.78 liters.
18.875mg * 3.78 liters = 71.35 mg.

So I would add 71.35 mg to 1 gallon of solution to raise nitrates by 0.125 ppm?
I guess it wouldn't matter if i'm on or off by a few but is this the correct way to calculate?

No, that is not correct. You calculated it for dosing 1 L, not 1 mL.

You also assumed what you are adding is pure phoshate.

I'd suggest using this calculator and the entry for potassium phosphate (which is close enough):
