Phosphate-X-globuli 1000ml Phosphate is a very important nutrient and should never miss. But if the water contains too much phosphate green algae and cyano-bacteria (blue-green algae) are growing rapidly. Hard corals will be destroyed because at high concentrations they are not able to synthesize their skeleton. In the modern reef aquaristic the phosphate...

POC+Globuli biopellets 1000ml In ultra-low NP aquaria POC+Globuli produce bacterio-plankton for the aquarium animals. The bacteria are ingested by filtrating organisms like corals and clams and supply them with energy and nutrients. In normal and highly polluted aquaria POC+Globuli are able to de-nitrify nitrate under anaerobic conditions: active...
