Great site here and thanks for adding me!! Bought a small, Bestway 12X22, 6K gallon, above ground pool from Costco last summer. It doesnt get much use, but nice to have on hot days here in California. I used a simple 2 way PH/Chlorine test kit, and was able to keep it looking good with that. THEN, decided to have Leslies do a test on my water sample, and it came back as my T A was very high. They said I needed a total of 19LBS of dry acid to correct the imbalance!! I had never even checked that before, but went ahead and followed their advice. I could not understand how adding that much acid would not throw off the ph, but started adding 12oz of dry acid a couple times a day. Spent a small fortune on their recommended chemicals, and checked my water everyday using test strips. Now, 2 weeks later, the Dang TA is STILL showing high, the ph is low, and seems like I am chasing my tail in a vicious circle adding ACID, then adding SODA ASH to try and keep PH in balance. Had the water retested at Leslies, and although T A came back slightly better, the printout said I still needed ANOTHER 13 lbs of ACID..... Im thinkin they just want to sell their chemicals, so turned to the internet. Thats when I found this site, and first learned of the air-ation (sp?) method to lower the TA in the Pool School. Not sure the stock wimpy pump in my pool has enough power to make bubbles, but considering trying that next, unless anyone has a better idea? Attached is the latest Leslies print out...... the high chlorine level is due to the fact I had just shocked the water the day before the sample was taken, but it has come down to acceptable level now. Still showing hi T C on my test strips though.... arrgh! Im still wanting to understand the expensive, acid/ soda ash crazieness cycle I have now found my self in...... for a layman!! Thanks again for a great site here!!!!
