If I mix a 1lb bag of calcium hypochlorite into 1gallon of water, what is the equivalent % strength to 1 gallon of bleach?

In your 24K pool, 16 ounces of 65% Cal-Hypo will increase FC by about 3.2. It takes about 3 quarts (98 ounces) of 10% liquid chlorine to do the same.
1 lb of 65% cal-hypo in one gallon results in 77,251 ppm (increase) or ~7.73% (77251 / 1000000 * 100).

*just have to add to make absolutely sure your mix bucket is sterile from whatever else it’s been used for. Pool chemicals go boom with just a trace of leftovers sometimes. The different forms of chlorine are particularly not fond of each other, for example.

A full bag of cal-hypo will not fully dissolve in a gallon of water so do be very sure to brush the granules around that settle to the bottom until they dissolve. Cal-hypo sitting against plaster can bleach the color from it. It also creates a highly alkaline solution that can easily cause cloudiness in the water due to the precipitation of calcium carbonate. That can take a long time to clear with a sand filter. Cal-hypo is better applied by broadcasting it around the perimeter of the pool while aiming towards the middle of the pool. Premixing a bucket of cal-hypo and water can cause a really noxious mixture that can give off some powerful chlorine odor.
just curious how your pool logs ch went from 300 to 100 in 3 months
a lot of water exchange?
