I am highly recommending Drylet’s Aqua Assist. It is working amazingly well at our ancient, in-dire-need-of-upgrading, extended aeration plant. Even with all the rags, grit, and other trash all swirling around these amazing bugs, they are still getting the job done well enough for me to want to recommend it to you. If you’re on the fence, all I can say is “go for it, and give it a try.” I’m certain that you won’t be disappointed.
