Lemme eliminate the easy stuff, first. That is, the stuff I can't answer: bees. The only idea I could come up with is to see if they are using your pool as a water source. If they are, you might could put a bird bath between your pool, and their home, and see if they'd use that, instead. Just a W.A.G. though.
I had thought of that before, thanks for reminding me. Yes, they are after the water, I had heard (I think from a beekeeper I spoke to once) that they not only consume it but use it with their wings for an evaporative cooler at the hive. Interesting.

"Frog Bam" (where do they get these names??) => MSDS at ChemQuip (Adobe PDF file)
-- Copper algicide --
Never used it, maybe because the name conjured up images of cars and frogs mingling. Having copper, looks like I'll never use it.

Since the mineral reservoir costs just shy of 100 dollars every year (plus another 80-90 bucks for a 6-pak Bac-Pac), if it doesn't provide substantial benefit then I'll probably drop that as well.

The ozonator is an UltraPure UPPX5, I tried to locate the manual online but no luck, the manual I have states on the front 'valveless suction side installation', so I don't know how that description fits with yours.

I'll have to check on the water report, just last week we received our annual municipal water report, but they only include regulated substances, I didn't see any minerals listed.

Also I was mistaken about getting cal-hypo locally, guess I'm still indoctrinated and haven't learned to read labels for myself. This question has probably been answered many times before, so sorry for being repetitious; the bags come in different strengths of active ingredient, like 48 or 52% of cal-hypo, and the rest is 'remaining ingredients'. Should I be looking for 100% active (doesn't seem likely to me), or are they all that way and are the inactive ingredients unimportant to know?

Thanks,
Dan
