Sell PET COLLAR✧❈♂Filter Brush koi ponds (30, 40, 60 cm ) best price

Pond filter brushes are usually used as a mechanical filter, placed before the biological stages in a pond filtration system. Filter brushes are very good at filtering out solids such as leaves, fish waste and string algae. Over time, brushes can become biological if care is taken when cleaning them. If rinsed with pond water every once in a while to keep the heavy solids off, beneficial bacteria will colonize on the polypropylene bristles, helping to clean the water on a biological level, although not enough to classify brushes as a dedicated biological filter.
