I am having trouble maintaining my PH levels. I guess I'm not sure what is considered a normal amount of muriatic acid, but I'm going through about a jug (gallon, 31.45%) a week. I'll bring PH down to 7.2 or even 7 and then a few days later it's 8+.
The only aeration I have is a water fall from spa to pool. It's about 2 feet wide and spills down about 1 foot straight into the pool. My TA is at 50 today and has slowly been heading down for about 6 months (was around 110 in the spring.) I'm not doing this on purpose, it's just going south. My usual maintenance is a jug of bleach every other day or so, and of course about half a jug of acid twice a week.
What's a good target TA? What is the effect of too high or too low TA? How do you raise and lower TA? Is this a normal amount of acid to use?
All other test are normal and water is clear.
Thanks in advance!
