Dramatically accelerates the colonisation of beneficial bacteria in your filters.
Filter Start Dramatically accelerates the colonisation of nitrifying and denitifying bacteria required for correctly maturing your filters.
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.
By maintaining and stabilising your water parameters, your fish suffer less stress, gill damage, injuries heal quicker and in severe cased fish losses are avoided. As the filters mature in time, and the pond finds its correct balance improved water clarity will occur.

A combination of minerals and enzymes for healthy bacterial reproduction and growth....
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 sources for blanket weed and green water.However, just like human beings, bacteria require a balance of minerals and trace elements to maximize their activity, development and reproduction. In our ponds the beneficial bacteria will, inevitably, take up and utilise the required elements that exist naturally in the pond water. Unfortunately, rainwater does not contain these essential minerals and they are not replaced naturally. Therefore it is essential for the fishkeeper to replace these elements back into the pond water. ‘Bacteria Conditioner’ contains all the correct mineral and trace elements to supplement the pond and the bacteria living within it. By maintaining and stabilising your water parameters, your fish suffer less stress, gill damage, injuries heal quicker and in severe cases, fish losses are avoided. As the filters mature in time and the pond finds its correct balance, improved water clarity will occur.
