Colombo Bactuur Filter Start 500ml for 2500litres - Ultra powerful filter activator

Filterstart is a starter bacteria for newly landscaped ponds and existing ponds, in the spring and after every cleaning you should give the filter a hand and balance the pond and you can do this by adding these live bacteria.

Like any other domestic animal, fish need a habitat kept in a perfectly clean state. Fish produce harmful ammonia but this will be transformed into harmless nitrate (via nitrites) in the filter thanks to the beneficial bacteria. Filter bacteria need time to grow. This is often the cause of problems encountered during startup. By regularly testing the water, you can check whether its quality is still correct.
