Jim, I had to go look up some of your IP addresses, to find out approximately where you are. Virginia is much more like Tennessee or N. Georgia, then like California . . . and I'm pretty sure we have more of a problem with algae than folks in S. California or Arizona.

Richard (Chem_Geek), Mark (mas985) and I have gotten an email discussion going about this that's probably up to 3,000 words in just a few hours. I guess we'll need to migrate it to the China Shop.

In your case, if I were you, I'd experiment with dropping the polyquat rather than the borates. Unless you are backwashing a LOT, you shouldn't be having to add borates much. One caution: polyquat is a pretty effective clarifier, so if that function is affecting your pool and you lose clarity you might try substituting a small dose of a conventional clarifier.

You might want to raise the borate level a bit. I still have no hard data, but it seems that 50 ppm may be the low end of the range for effective algae-stasis.

Best wishes!
