Bleach in hot tub

[sevver]

I just reopened my hot tub, the guy I sold it to has not came for it and it has been sort of empty for around two weeks. I did not want it getting nasty so I reopened it. I have it on the BBB method and it does not take much to do something drastic to it. I have gone the extreme on the PH each direction a few times now. And I figured that the bleach would not take alot so I have been careful with it.

As for the PH though, I tested the TA and it is around 50, I need to get that up and I am sure the PH will be a bit more stable. I believe Baking Soda will do that, I am going to mess with that tomorrow after work. I have been using Borax and Muratic Acid to go either way, and the Borax does not raise the TA, so I will substitute it for Baking Soda.

I think the hot tub is a neat little test area, great for quickly seeing results and showing you respect for the quantity of the chemicals you use and its effect on things.

I am much happier using chlorine ( bleach or di chlor ) than the bromine method. Everyone in the family says the water is less harsh and no odors. And we have much less foaming and the water is crystal clear. But you have to add a little chlorine EVERY day. Chlorine is less stable at the higher temps. Add the chlorine right after you use the tub, not before. You will find that the next day, it will be gone,but that is OK. If the tub is covered, it should remain relatively sanitized until your next dose that day.

One thing, it is always more work to keep the alkalinity ( and thus pH) adjusted in a hot tub because of the aeration. I check the alkalinity regularly and add baking soda as needed. then you can adjust the pH as needed, but not before adjusting the alk. I tend to run my alk ( and pH) a little high so that it stays in the normal range longer.
