What's all the acid for? Maintaining PH?
I have a hot tub and all I have to do is keep the bromine floater full and for some reason it takes a lot of sodium carbonate or whatever that stuff is because my PH is always going down on its own (and I don't piss in it, lol)
I also use that foam away stuff once in a while.
Yes, the acid reduced the PH which rises slowly due to the Salt water generator. Considering I never have to add chlorine or use the pucks, which raise the CYA levels it is pretty low maintenance. I've had a Salt pool and a regular pool and I would not go back to the regular again.
I went chlorine for my hot tub. I use the Nature 2 cartridge in the filter area and just shock the tub with a capful of spa shock after each use, or if not in use a capful per week and it's good to go. No other chemicals needed since I change the water every 4 months and the ph levels stay in the normal range. I do add a bottle of Metal B Gon upon each refill.
