Water Gardens — Clean ponds

WHAT is the best way to keep a pond clean? I am considering installing one, but have seen so many mucky, problematic water gardens that I am put off.


THE answer is GOOD MANAGEMENT. Do not over stock, do not over feed, use only good quality fish food and keep organic matter, such as leaves and grass clippings, out and plant heavily with water plants.

Also, you should have a good bio-filter and UV clarifier, a quality pump and you should regularly use a biological additive.

These last items are not an alternative to good management but, used in conjunction with it, will ensure a clean, healthy and trouble-free pond.

Having said all this, a pond will always have some organic matter in it and will never be as clean as a swimming pool. If this is your desire, you will be disappointed.
