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
