We started out our new swim spa with chlorine 2 weeks ago. When we had problems balancing things and had cloudy water, the spa store told us "it will clear up" and said to only add chlorine once a week, no matter what the test strips say. Well, we ended up with bacteria and my kids got bacterial hot tub rash badly. The spa store said since we were having such a hard time balancing things, we should switch to bromine. Now, from what I have been reading here, it sounds like chlorine would be better for us since we are in it quite often. I have just refilled it and put the metal protectant in and then tested it at spa store yesterday to try to get alk and ph balanced. Thank goodness, my Taylor test kit was delivered today, so I can now test it myself without those dang strips (and without relying on spa store)! Anyway, I would love advice on this. I know my spa is bigger than most since it is a swim spa, but I would think it would be the same as any smaller spa too. Thanks in advance!
