To get a good insight into what is good water for fish, it is important to understand first what takes place in a fishpond. Of course a fishpond must be attractive to the eye. But in fact, a pond is nothing more than a reservoir inhabited by excrements-producing fish that pollute their own living environment 24 hours a day. The quicker such waste products are removed from the system, the better the water quality. When there is a smaller amount of dirt, the required bacteria will flourish better, which improves the pond filter operation. Most of the oxygen in the water will then be available to the fish to help their metabolism. This process is decisive for their well-being and growth. This is why it is vital that the produced waste substances are removed quickly, adequately and regularly. If your pond system and your pond filter system manage to do this, you will have optimum water quality and growth conditions for your fish in the fishpond.
