Hot Tub Question

[waterbear]

If this is an indoor hot tub then you DO NOT want any CYA (stabilizer) in the water. If the hot tub has it's own filter and pump you might want to consider bromine instead of chlorine. If it share the pool water you don't have a choice but stabilizer is NOT good in a hot tub that is not exposed to the sun. If you decide to use chlorine and there is not CYA in the water then just keep the chlorine leves at about 4-6 ppm with bleach. I would try and find out more about the filtration and plumbing between the hot tub and the pool. Also, If this is an acrylic tub with molded seats the volume of water is going to be less than if it were a tub that had an even depth all over. What are the dimesions and shape. Most acrylic hot tubs are under 500 gallons and your typical 6 foot round is about 250-300 gallons!
