The Undergravel filter will give your goldfish home a health start. Keeping the water purified and clean is the most important part of fish keeping and one of the main causes of fish becoming unwell. The filter will trap suspended waste and biologically remove toxic fish waste creating a clear healthy aquarium. Attach the filter to an air pump to create water circulation and flow needed to use the good bacteria in the gravel to break down the waste.
