Bac-Pac is the name of the tri-chlor cartridge for the Pool Frog. I have been using dichlor for shocking, which I now realize also contributed to increased CYA. Will stop using that, and just use bleach.

Can't even locate the cal-hypo locally, guess I'll have to order online.

Any suggestions as to how I can get rid of the scale ring? I've tried various things like pumice stone (way too much elbow grease required for that) and some chemical that you put in the water when it was cooler and raised the water level for a while. Can't find the product online now, but it came in a quart jug and was a red color. That didn't do anything. I've read that lowering the pH would help it start to loosen up, is that recommended?

One other thing that's not chemical related, but I'm hoping someone here can point me in the right direction. We have a big problem with honeybees, they show up in the early morning and the late afternoon, which is our prime swimming time. I've searched the web in vain and tried various things like mothballs and sound waves (how geeky is that!) to no avail. Seems like the only solution I've found so far is hiring a beekeeper and have them hunt down the hive and destroy it. Since these are most likely wild (we live on the edge of the desert mountains), that sounds expensive and difficult. Anyway, I don't really want to destroy these beneficial creatures (even though we have to use spray just to keep them reasonable enough to swim), I just want them to go away. I wouldn't mind so much if they were helping to pay for the pool!
