Hi, I have a .25 acre pond in south La. All clay.
I am noticing alot of black looks algea or somethting on top the water and some settling on the bottom edges of the pond. Anyone know what this is? So, can someone point in the right direction as to what type, size and place to get an aereator. I am clueless when it comes to this. Cost is an issue for me right now also.

Thanks
