I am trying to cut costs by buying bromine tabs in bulk. My local Costco has a larg pale of Bromine tabs for pool, the guarantee available bromine on the lable is close to the tabs i am currently using in my spa.
Pool tabs: Available bromine present as 1-bromo-3-chloro-5.5-dimethylhydantoin......61% Available chlorine, present as 1-bromo-3-chloro-5.5-dimethylhydantoin....27%
Spa tabs (Omni for hot tubs and spas): Available bromine present as 1-bromo-3-chloro-5.5-dimethylhdantoin.....64% Available chlorine present as 1-bromo-3-chloro-5.5-dimethylhdantoin.....28%
Can i use the pool tabs for spa and is there a shelf life on bromine tabs?
