I have been trying to understand the more advanced concepts of what is happening to the chlorine in the water. I came across this article about "Water Treatment To Prevent Emitter Plugging"

It looks like it would be helpful to lower the pH to near the load end of the acceptable range in order to get the most effect from the chlorine when fighting algae, especially cleaning up a swamp.
Your comments please.
