Velda - Bio-Oxydator - Brochure

Fallen leaves, died off water plants and excrements of fish can increasingly pollute the pond bottom. Lack of oxygen will acidify the pond soil, whereas decomposition of organic sludge is no longer possible. The water plants will no longer grow and algae will gain the upper hand. Bio-Oxydator removes sludge from the pond bottom and will prevent new sludge from forming.
