Pond Filters
Depending on the size of your pond and how many fish you have will determine the type and size of the pond filter you need.
It's important to realise that a pond filter is first and foremost required to purify the pond water ... fish pollute the water as part of their natural metabolism and if the impurities are not removed toxic levels of pollutants are reached. In such circumstances fish would become stressed and might even die.
