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 your tank. Your plants can draw on plentiful resources again and will thank you with lush growth. Especially fast growers like Glossostigma elatinoides benefit from this fertilizer.

Weekly water changes of 25% to 50% are recommendable. The dosage can be raised or lowered depending on your requirements. If your tank water shows high readings of nitrate and/or phosphate from the start, this fertilizer is not suitable for your aquarium, though. Makro Special Light has been designed to prevent the accumulation of large concentrations of macronutrients. If high levels of nitrate and/or phosphate occur, please reduce the dosage.

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 your 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.
