Swimming pool chlorine and household bleach are both Sodium Hypochlorite.
Just calculate which is cheaper to buy. The pool chlorine is 2-3 times
the
strength of normal bleach. And Ultra Clorox is about 1/3 stronger than
standard bleach.

The last time I looked at the packaged pool chlorine it worked out to
the same price as no name laundry bleach but we can buy pool chlorine
from the pool store in bulk for less than half of what the packaged
product costs. There is also the problem that all of this tends to
deteriorate over time so that 10% chlorine in the Jug at Home Depot
may only be 8 or 9% if it has a lot of dust on the bottle. My pool
store turns over several hundred gallons a week so it is always
fresh..
I get my liquid at the pool store. Since this is California the bleach
costs extra cause it is a chemical. Normal clorination is via tablets.
Every couple of years I dump part of the pool and add fresh water to lower
the stabilizer levels. Works for me. And with the solar heater, I do run a
comfortable pool in the summer time.
