Greg Grimes offers his recipe for Pithophora control in southern soft waters:
This is what we do. Shawn Banks will tell you our mix works better for us in the SE than in the midwest because our water is so soft (see there is some advantage to having poor water quality)

Mix with a gallon of water:

8 ozs Ktea, Cutrine+, or other chelated copper herbicide, etc. (8% liquid copper)
4 ozs Reward
1 ozs surfactant, also called an adjuvant, examples "Cide Kick II, Cygnet Plus"

It will require couple of treatments.

This what come with experience and the problem with blanket algae statement on how to mix BUT

we give a good mist on the Pithophora, you can see it at this rate will lightly turn the alage blue. You do not have to hit it too hard but also if you spray one area and miss another area it is not giong to kill the missed area. You expect to miss some thus the reason for mutiple applications. THis combo will save quite a bit of money vs. using Reward alone. Hope this helps.
