Oase AquaActiv PhosLess Direct 500 ml, product type

Algae protection physically removes the algae nutrient phosphate. It binds hydrogen sulfides, which can cause foul odors. This provides quick relief for elevated phosphate levels. It binds excess phosphates, thereby naturally reducing algae growth. 100 ml can bind up to 22 g of phosphate. Algae thrive on phosphates, which primarily enter the water through fish feed. Especially during the winter, after an algae treatment, and with constant phosphate input, the free availability in pond water should be kept very low. Binding phosphates is an environmentally friendly measure to proactively counteract algae growth without using biocides.
