Commercial fertilizer doses, scaled to your tank.
Doses come from each maker's own product page. We show the ppm a dose adds where the label makes that possible, and mark anything we had to assume.
Dosing on — L. Tick products to build a mixed plan; edit mL and doses per week to match how you actually dose.

How to read the numbers. "Label" = the maker states the concentration or the ppm a dose gives. "Assumed density" = the label gives % by weight, and we assume 1 mL weighs 1 g, which slightly understates ppm for denser liquids. Nitrogen products are shown as nitrate-equivalent; part of their nitrogen is ammonium/urea that a nitrate test won't read.
