Thanks! I had done a little reading on it, but wondered if it was like so many other things in the ponding world where you question its efficacy and is it more of a "fad" thing. So from what I gather, it does have a legit benefit, but it's not something you have to have.
I read a few things where people said it "gummed" up their filters. Any feedback on this?
And what happens if you don't use it like they recommend [weekly applications], but only use it periodically? Would there still be any benefits from it, or is it an all-or-nothing additive?
