Full Potassium Fertilizer
For strongly planted and strongly lighted pools, potassium can be a limiting factor, as many plants take-up much more potassium than they need.
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.
One should start only with a small part (a sensible amount would be 20 - 30 %) of the Ferrdrakon dose, replaced with Ferrdrakon K and the replaced part should be only slowly increased. The effect should be observed: When there is no more growth improvement and/or problems with algae begin, one must reduce the replaced part-dosage again.
Ideal iron content
0.05 - 0.1 mg/l
Ideal 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.
