Water Gardening: How to keep pond clean?, 1 by weed_woman

Thanks Andy!
The water is rain/tank water as we aren't connected to mains here, and It is possible that when I potted the plants, there might have been slow release fert in the mix! I don't feed the fish as I think there must be plenty of little things living in the pond, due to seeing dragon flies, frogs, water snails and other unidentifiable creatures splashing about, But DH has an obsession with the pond and does tend to overfeed, against my advice/nagging, so that could definitely be an issue.
I've used a type of bentonite in my dam to seal it (Not worked all that well) So It may be that I can track down the one you have suggested and see how that goes. I do hope to have power on near the pond in the future, when I will install a bucket of bio-balls and a pump. I wonder how the clay would affect that, do you think? I suppose that as long as the pump inlet isn't down in the clay it should be alright.
Anyway, stuff to think on.
