Aquatic Plant Fertz Question (K Solution)

[Tyger]

Greetings Folks,

I guess that I will start by saying that I have an aquarium that tends to have more than enough phosphates (P) and nitrates (K) created through the ecosystem in the aquarium. In terms of fertilizer dosing, I am planning to custom mixture using a rotational system described by Guitarfish (cf., What I Do) based around a hybrid of Perceptual Preservation System. In any case, I have read and created SS, NF, PF, Mg, & TE mixtures w/plans to create K mixture and GM Booster Solutions. Unfortunately, PPS does not describe the creation of K Solution (using Potassium Sulfate [cf., K Solution Pfertz]). As a result, I was wondering whether someone has done the research and has recommended dry fertizilation amounts for mixing a 450 ml bottle with an appropriate dosing regime (vs direct teaspoon dry dosing to aquarium).

Thank-you, in advance, for thoughts, guidance, and advice,

~Tyger (Michael)~
