Full Potassium Fertilizer - Refill Package

For strongly planted and strongly lighted pools, potassium can be a limiting factor, as many plants take-up much more potassium than they need.

Before use please dissolve according to this guide.

Ingredients

30,000 mg/l potassium, 7,500 mg/l magnesium, 500 mg/l iron, 200 mg/l manganese, 100 mg/l calcium, 30 mg/l boron, 10 mg/l copper, 10 mg/l molybdenum, 10 mg/l zinc, 5 mg/l nickel, 5 mg/l cobalt, 4.6 mg/l iodide, EDTA, HEEDTA, DTPA, NTA, methyl paraben, ascorbic acid

Dosage

Ferrdrakon K should always only replace a part of the Ferrdrakon dosage. One starts at the calculated or recommended dosage of Ferrdrakon and replaces a part with the double amount of Ferrdrakon K. By using it on its own, the potassium dosage in practically every case would be too high.

For the replaced part the potassium and magnesium dosage is 20 times higher than before.

Optimum iron content: 0.05 - 0.1 mg/l
Optimum potassium content: ~ 10 - 15 mg/l

The overdosing of potassium can cause an exorbitant growth of green algae or insufficiency symptoms by blocking the absorption of magnesium.
