Filter Start dramatically accelerates the colonisation of nitrifying and denitifying bacteria required for correctly maturing your filters in easy to dose tablet form. Filter Start contains the correct balance of several groups of bacteria that are best suited to colonise a new sterile filter in conjunction with a stocked fish pond. This enables stable healthy water conditions to develop therefore a healthier environment for your fish.

By Maintaining your filter with the correct balance of beneficial bacteria, you help to ensure that your filter will nitrify to its optimum, (removal of ammonia and nitrite that fish excrete due to respiration and digestion). Phosphates and nitrates will also be reduced, (denitrification) which are the main food source for blanket weed and green water.
