Tetra Pond FilterStart is a filter activator designed to kickstart your pond filter after winter or when setting up a new pond. It extends the intervals between cleaning by utilizing beneficial bacteria. These bacteria help reduce pollutants like ammonia and nitrite, and break down organic waste such as fish excrement and foliage. This leads to a cleaner pond environment and reduces the need for frequent filter maintenance. Tetra Pond FilterStart also helps build organic turbid materials thanks to special cleaning bacteria, increasing the service life of pond filters and prolonging cleaning intervals. It effectively reduces pond contamination by live filter bacteria, specifically targeting ammonium and nitrite.
