probably lots of interest in this topic, I certainly am
I think Marci, you will find these additives to be 'anti-fungal' only in the sense of having a somewhat low pH, the low pH inhibits blah blah
but they do work
I investigated additives strictly as an algaecide, and there are many
but what I found was that they all will come out of solution leaving even more of the pesky white residue - but nothing was growing !
I think an essential requirement is that the algaecide go into solution and not precipitate, this may be difficult given the UNIVERSAL tendency to overuse
are we asking the right question: if the low pH inhibitors 'work', what are we looking for ?
