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 Licht brings the important macronutrients nitrogen, potassium and phosphate into the aquarium. The plants can once again access plentiful resources, resulting in lush growth as an expression of gratitude. Especially fast-growing plants like Glossostigma elatinoides benefit from this fertilizer.

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 and/or phosphate from the start, this fertilizer is not suitable, though. Makro Spezial Licht has been designed to prevent the accumulation of large concentrations of macronutrients. If high levels of nitrate and/or phosphate occur, the dosage should be reduced.

The basic supply of macronutrients in a tank with soil-based substrate is provided by our waterplant fertilizers Makro Spezial Licht (nitrate, phosphate and potassium), Makro Spezial K (potassium) and Special N (nitrate). Our waterplant fertilizer Aqua Rebell Makro Spezial Licht has especially been designed for the use in aquariums with a soil-based substrate and fast-growing plants like Glossostigma elatinoides. Makro Spezial Licht closes gaps in the nutrient supply of the soil substrate and thus promotes the healthy growth of the waterplants.

Our waterplant fertilizer Makro Spezial Licht adds mostly phosphate and can thus of course also be used as phosphate fertilizer in tanks without a soil-based substrate.
