Jimmy;
I agree with the previous post, with the hot & dry weather we've had you're likely to see some algae. I also agree that the grass carp aren't likely to eat your cattails. If you're concerned about algae Israeli carp might be a possibility. I put 12 israeli's and 10 koi in my 1/3 acre pond to control alage and they seem to be working fine. By the way, I'm from the northeast pa area (tunkhannock), where in n.e. pa is your place ?
