How To Keep Water Safe...

[DavidPenniall]

Have had a pond in back garden since moving into my house some years ago, however it has regularly been a dirty pool of water. My sister once cleaned the pool out and put fish in however they died in the winter when the frost came. How would I create an all year round set up where the water may not freeze and the water will not go green a dirty? Thanks.

Did you use a filter? if not it would help keep the water cleaner and the flow of the water would prevent it from freezing over (as long as it's not really really cold)

Ponds need to be at least 2.5 feet deep for fish to overwinter safely, and you must keep at least part of the pond clear of ice.

Does this pond have a filter at all? Adding a UV light to it would clump up the algae that's turning your water green, allowing the filter to catch it.

If not (and all ponds with fish in should have a filter) you could try adding some floating plants (duckweed is good, and a great nitrate eater too) that will stop so much light reaching the water and that would help too.

The deepest point is roughly 1.6ft deep, does this mean the pond is pretty much useless and might as well be dug out and filled in?

It would be fine for a wildlife pond at that depth, just not for fish, I'm afraid.
