Update 8/5/19:
I've applied diquot/copper to the coontail, and it definitely gets better, however it just grows back again. I have been treating 25% of the pond every 2 weeks.
The instructions say that its necessary to wait at least 2 weeks, but by that time the first area of the pond to be eradicated is already growing back.
I have good aeration going which should help reduce any oxygen drop from plant decay.
Can I do the treatments one week apart instead of two? I think that would be close enough to wipe it out before it can grow back again.
