All About the Product

Product description

Bactoplus Filter Start Gel – Filter Bacteria Starter for Pond Filters

Bactoplus Filter Start Gel contains highly concentrated living filter bacteria that support the biological filtration process in the pond. The contained bacterial strains convert harmful ammonia into nitrite first and then into nitrate, thereby contributing to the stabilization of water quality.

The gel contains both AOB (Ammonia Oxidizing Bacteria) and NOB (Nitrite Oxidizing Bacteria), which together ensure efficient biological filter performance. This supports the nitrogen cycle in the pond and breaks down harmful substances more quickly.

The gel consistency makes it possible to apply the bacteria directly to the filter material, allowing them to settle there optimally. Bactoplus Filter Start Gel is particularly helpful for the start-up of a new filter, after filter cleaning, or in the event of water quality issues to support the rapid development of filter biology.

The product is ideal for koi and garden ponds and ensures stable biological filter performance.
