darrell,
I agree also that they will be back. Tilapia have worked great for me on algae control. Grass carp have worked great on pond weed...the only problem I've had is keeping the grass carp in the pond. I have to have fish gates across spillways to keep them in.
My thoughts are to stock some grass carp this fall, it's a good time to handle them, and treat the algae with Cutrine plus. If you stock Tilapia next spring, they can get ahead of the algae much quicker if you use the Cutrine now to help get it in check. Once Tilapia get ahead of the algae, in my ponds at least, they stay ahead of it. I don't like to use chemicals either, only when required, and fall and early spring seem to be the safest times to use them because of water temps and normal good rains.
