Hi HopHop, welcome to the group. As for the little black things in your water, it sounds like they could be mosquito larvae. As for the water going milky, it could be a bacterial bloom which should clear up shortly once the water balances. If your water continues to be milky, it could be that it needs a biological filter. I have a diagram of a really good one that can be found at our clubs website at: www.geocities.com/ont_pondkeper

Yours Koily, Lorraine
