I've noted that chemicals come in food grade, reagent grade etc.
Stump grade to be used as an additive to my systems would make me more than cautious. Any number of what the mfg believes to be inert (for the labeled and applied legal applicaiton that is more than likely on the package) may become ert in saltwater. Who knows? Also who knows what impurities of a heavy metal variety that could build up and nuke the system are present in the stump grade stuff?
And making a statement that the nitrate worked for being the growth trigger without having a test of the Potassium before you dosed before and after is really just speculation. And what other possible changes were happening etc? And not doing a comparative test with two identical systems with equal amounts of livestock, water volume and equipment makes the result again speculative (test v control better approach) and really just a lucky crap shoot at the best description. So many things have been stumbled upon in science it's not even funny. However, 1 observation in 1 system without a comparison is just bad method.
But, Glad it worked out so far and you didn't shock anything for losses are a bummer.
Well I looked at some Kno3 from well known chemical store, but the data was pretty much exactly the same as the data for the stump remover. I did my homework and both fresh and saltwater planted tank aquarists use stump remover to boost plant growth and to save money. I have yet to read of anything detrimental occurring. I have also only needed to dose once as of yet my nitrates are still hovering above 0. So unless my colors begin fading or growth slows continued dosing may be infrequent.
