Would like to switch to bleach only but...

Most pools seem to lose about 2ppm daily. That can vary widely but, let's take two examples.

If you lose 2ppm daily, 1 quart of 6% Clorox will replenish it.

If you lose 4ppm daily, (possible in the full Sun), of course, 1/2 gallon daily will be your usage.

So, somewhere between 7-15 gallons monthly would be most likely. With that VERY high CYA, you may get by with even less.

Regardless, you really need to get off pucks.

By the way, those are VERY nice test results....just about perfect. Nice work!

PS - Your two toddlers fight? Gosh, I can't imagine!! (Yeah, right! My two are still at it strong @ 13 and 11....been going at it for almost 10 years!......Sorry to deliver any depressing news )
