I am using regular bleach - either clorox or generic "publix" brand (publix is a regional grocer here in the southeast). I buy the big 1.42 gal size, and dump half of it in every other day, which seems to get me to 3 or slightly higher.

Here's another question: Will a full jug of bleach take exactly 2x longer to dissipate than half a jug, given the same weather and exposure and same pool, and all other chemicals being balanced, and no additional chlorine demand? I don't think I have *any* algae, as I can't see any, and no slimy surfaces.
