Hi All,
Ive got a large lined pond, approximately 100x50, somewhat kidney shaped that varies in depth from the shallow end that gradually slopes to the deep end, around 6'-7'. I have a fountain in the pond and now an aerator at the deep end. The aerator was a recommendation from the local pond shop to help clear up the water. It was added as soon as the ice cleared from the pond this spring. The problem is that the water is still really cloudy and it appears that after a few months of aeration the only thing thing it has done is churn up a bunch of debris and cause what looks like swirling algae in the water. The water is much worse now. I tried adding midnight blue dye to the water but it still looks very green. I've put buckets of muck away in. I was in the pond yesterday. There's not much on the bottom except what feels like some rotting leaves and the sides are clean except the slippery algae. I'm looking for some recommendations to help clear the water so the family will be interested in swimming. Can I retrofit a large filter and pump? Should I try adding plants? Should I just let the aeration continue in hopes that it eventually helps? I've got quite a few goldfish/koi in the pond added from the previous owner. Do I have to drain the pond to make changes? Help! Thanks all!
