Ok, the new spa will be here in a couple of days. Everyone has eased my mind a bit on the whole "chem nightmare" thing. I am going to try the BBB method first. I have a TF-100 test kit on the way. I also bought the chems to go the bromine route later on if I don't like the BBB method. I have been told that with my small tub (270g), borates to 50ppm will work wonders. I have a few questions...
How much borax do I need to add initially to get to the 50ppm level?
I plan on keeping the spa in my basement. Do you think I will have to worry about moisture causing mold and mildew? The reason I ask is, one guy on another forum said he would be worried about mushrooms growing from the ceiling. I do have a dehumidifier I can run during the summer and fall. I'm not so much worried about the colder months because I heat with a large wood furnace and the air gets very dry if I don't run a humidifier, so no worries in the colder months.
Thanks for all of the help. I am more confident that I will be able to get the tub in check.
