Sera® Pond Phosvec 500ml
Phosphate is the most important algae nutrient. In the garden pond it accumulates quickly as a degradation product. A massive and therefore dangerous increase in algae is then almost always the result. sera pond phosvec binds phosphate quickly, gently and permanently. The uncontrolled proliferation of disturbing algae is prevented from the outset by this effective, sustainable prophylaxis through nutrient limitation and stopped in the long term.
