    Adding bleach to hot tub

    OK, all you spa Dichlor/Bleach practitioners, I’m curious as to how you actually add bleach to your hot tub on a regular basis. My wife and I are senior citizens and more than a little shaky when it comes to pouring out and adding a couple ounces of Clorox bleach to the tub. Historically...

    Pool Auto-Pilot?
