need to know how much of mrs. stewart's bluing to add to the 24' X 4' high, round swimming pool?

Answer 1

Mrs Stewart's Bluing is an additive for laundry, not for pools. Standard fabric or laundry clorine is not the same as the clorine used in pools. Even Walmart carries the inexpensive swimming pool stabilizer which you need. (They have one which I use which is a container that simply floats on the surface of the pool and will slowly add clorine in small amounts so I don't have to add it daily. This floater lasts about 3 weeks and costs me less than $20.00)

Most all swimming pool chemicals will have instructions on the side for the amounts to add per the number of gallons in your pool. Your pool has approximately 13,535 gallons of water, so use that in your figuring.
