Hi all, I've just opened my 25,000 in ground pool. The first thing I did was shock it and add some algaecide to clear it up. Testing my water this morning (with a test strip) I found that my PH was normal but my TA and Hardness were both very high. Previously when my TA was high, my PH was also. This is a first for me. I'm new to this forum, but I've learned by searching around that;
A: testing with a strip is not the best way to manage pool chemistry.
B: My problem is not unusual.
C: TA takes a while to lower.

I read the link in "Pool Solutions" by Ben Powell about lowering TA. He says to use small doses of acid and to aerate the pool. My questions are, what is a "small dose" for a 25,000 gallon pool? How often do I add the dosage? How often do I test?
Thanks all
