Pool looks great!!!
Good and the bad. Let's start with the good. I went to my local pool store to pick up some Muriatic Acid and let them test my water to get a comparison on my test. I can't say when I had more fun thanks to you guys and the BBB Method. The lady in front of me struck up a conversation and commented how every time she comes in here her pool needs something. The pool store guy did her test and told her how it wasn't too bad as she paid her $175 for PhosFree and other chemicals she probably didn't need. She watched as he did mine and I asked him not to bother with the phosphates part of the test. I paid my $12 bucks for two gallons of acid and she said "How come..." All I could say was I try to stay on top of it. I didn't want to get in to it with the pool store guy so I left it alone even though I wanted to tell her about this site and the BBB Method. I exited with a smile on my face, thinking if it wasn't for my new plaster I wouldn't have even have bought the acid. Now the bad. Due to the fact that I'm using a lot of acid my TA has dropped to 70. The pool guy naturally said I should add about 3 lbs of Alkalinity Up to try to get the TA up to 100. I told him I had some at home but I was wondering if I'm OK at 70 since the TA seems to keep dropping with all the Muriatic acid I keep adding every few days. What would be a good number to shoot for and should I start adding Baking Powder now or wait till it drops below 70.
Thanks in advance
