Well the weather in the midwest is finally acting like summer and the ark building has been put on hold. In usual fashion the pond is starting to get the green algae film on top. Last year I used Cutrine Plus (liquid) and Aqua shade....both worked like a charm and cleared her up with no issues.

This year is a little different....or so I have been told. We have the pond stocked (last fall) with around 1800 fish....200 being channel cat. I was told that I should not use Cutrine Plus (or any copper based algaecides) if I have channel cat. Thoughts? Solutions? Thanks in advance!
