- Worth noticing
- It notes that KNO₃ contributes potassium as well as nitrate, and explains when extra K₂SO₄ may be needed.
Field notes
The inputs distinguish nominal tank volume from estimated net water after substrate, rock, and wood. Guidance explains that KNO₃ already contributes potassium, while magnesium dosing may be unnecessary with moderately hard or hard tap water. The page also warns against combining phosphate and iron in one bottle, and recommends stock-solution mode for doses below about 50 mg.
