DIY Nitrate Dosing with Gordon's Stump remover

[Bulletsponge]

Has anyone used Gordon's Stump remover to make a DIY nitrate solution to dose for a reef tank? The label says 99% Potassium Nitrate and 1% Calcium Stearate. Unsure if the calcium stearate has any effect on the solution or the reef tank. Spectracide stump remover lists 100% Potassium Nitrate but from what I've read, it probably has impurities as well. Only reason I am asking is because I can buy Gordon's locally and would have to order the spectracide or another source. Thanks in advance

The calcium stearate is no concern, but I’d recommend a product with a purity assurance that is not provided by an ingredient list, which is what yours is likely to be. Food grade sodium or potassium nitrate are both available and not very expensive.

is there a food grade / hi purity lanthanum product for phosphate removal ? Kinda off topic but kinda on.
thanks in advance.

This is where I got dry ferts from when I was heavy into planted tanks;

Aquarium Fertilizer – Planted Aquarium Fertilizer | Napa, CA

Hopefully a little purer than stump remover.

there is pharmaceutical lanthanum for phosphate binding in people, but I do not know if it is available to the public.

I’d still get food grade.

Those numbers were off the MSDS sheet i believe. Accurate enough or no? I have a walmart in my town but they don't carry the spectracide stump remover. The gordon's is at an Ace Hardware or Tractor Supply. I don't suppose waiting an extra day or 2 will hurt but I've lost sps frags to Dino/low nutrients. and want to either solve the problem by dosing or at least eliminate that possibility.
