In a strongly lit well-planted tank or in aquariums with few fish a lack of macronutrients may occur, which in turn can lead to poor plant growth. Makro Spezial N brings the important macronutrients nitrogen, potassium, magnesium and calcium into the aquarium. The plants can once again access plentiful resources, resulting in lush growth as an expression of gratitude.

Weekly water changes of 25 - 50 % are recommendable. The dosage can be raised or lowered depending on the requirements. If the aquarium water shows high readings of nitrate from the start, this fertilizer is not suitable, though. It has been designed to prevent the accumulation of large concentrations of macronutrients. If high levels of nitrate occur, the dosage should be reduced. When the pH of the aquarium water exceeds 7, the formation of ammonia can not be totally avoided. It is therefore recommended to use the fertiliser with caution.

The basic supply of macronutrients in a tank with soil-based substrate is provided by our waterplant fertilisers Makro Spezial Licht (nitrate, phosphate and potassium), Makro Spezial K (potassium) and Special N (nitrate). Our waterplant fertilizer Aqua Rebell Makro Spezial N is necessary to supply the aquarium with nitrogen. It is manufactured from several different nitrate salts and thus adds small amounts of potassium as well as some calcium and magnesium.

Especially aquatic plants like Hemianthus callitrichoides "Cuba" show a very positive reaction to the addition of Makro Spezial N. The waterplants will attain more intensive colours and grow healthily. Of course, Makro Spezial N can also be used in tanks without a soil-based substrate, all waterplants benefit from the use of this fertilizer.

A fifth of all the nitrate contained in it consists of highly mineralised carbamide. Thus, 0.2 mg/l NO3 get into the tank through carbamide, which is first mineralised to ammonium and after that to nitrate. The plants can already use carbamide as well as ammonium, and for some species, these substances are even the preferred source of nitrogen. Thus, the nitrogen supply is safeguarded by various sources, and the waterplants get their optimal provision of nutrients for healthy growth.

Sehr guter N-Dünger, bin voll davon überzeugt. Der K-Anteil wird nicht zu stark, Calcium und Magnesium dafür aber mit aufgedüngt. Sehr empfehlenswert!
