I've read that liquid ACH is a very effective flocculant that will not hurt fish. Application is much easier than with alum and does not affect pH. Just wondered why it has never been mentioned in this forum or if there are negatives associated with this product that I'm not aware of.
Results with alum are temporary. Aeration stirs up clay particles and increases murkiness. I could have saved a step in dosing the water with baraclear and microbes and just tossed money in instead. Runoff is not an issue as the entire perimeter slopes away from the water and there are no areas void of vegetation. Several times a year the water is crystal clear, especially after periods of rain or ice melt. Any ideas?
