I just wanted to pop a note in here to say that adding borates to the pool has done amazing things for my chemistry.
We just moved into our house on Oct 31, and I started to maintain our pool. I fought with the chemistry for 6 weeks. My ph was always high, my TA was high. I would add muriatic acid to the water, to get the ph down. It would come down, then I'd aerate the pool to get the TA down, the ph would get out of hand again. I went through a 4 litre jug of acid in a month, which I think is excessive.
Then I added the borates to the pool, and I haven't had to adjust my TA or ph since!
I was going to use the borax/acid method, but ended up finding a ph neutral borate to add.
For those of you who are in Canada, you might want to consider purchasing Capo's Soft Touch Conditioner.
It works the same as the other products mentioned in the thread, but it's made in Hamilton, ON, therefore it's about $15 less per 50 lb container.
This is definitely the best thing I've done for the pool, and I'd recommend it to anyone who is trying to balance their water. It's also helped out with the softness in the water, which is great because we spend a lot of time in the pool in the winter.
