tman, great post thanks for that infor. Gomboman, I have had zero issues with bromine since I got my tub. I dont know anything else, but I cant find dichlor locally. All the dealers here really push bromine.
The only thing that I like about bromine is that I can add it once a week or two weeks and leave the tub. This helps because I travel alot with my family and dont like calling people and asking them to care for my water.
So, Tman, can I just add baking soda to my tub. Does this really work? I am sick of paying 15.00 a month for alkalinity chemical.
