Just within the last week, I've had a major (bloom?) of a reddish-brown algae. It now covers over 2/3 of my one acre catfish pond.

Times are tough here in East Texas. Severe drought. Pond is down abou 50%. Deepest area is now only 5'.

I do have a recirculating pump dropping water back into the pond adding some oxygen.

What is this stuff, and what am I up against?

Plant Oak Trees!
Catch Tarpon!!
