I went to the pool store today for some Boxer adhesive and while I was there I decided to get a free water check and here is what I found out:
CYA 60
Total Chlorine 3.7
Free Chlorine 3.6
pH 7.2
Total Alk 67
Adj. total alk 49 (don't know what that means other than adjusted)
Total hardness 68
My pool is a 24 x 52 above ground vinyl liner with 13,500 gallons. She said that my ph and alkalinity need adjusting (as well as calcium but I've been a member of this forum long enough to know that adjusting calcium is bull for a vinyl lined pool). I read in another post that a pH of 7.3 was okay so I am wondering about my 7.2. Also, when I do the alkalinity test at home my reading is 120. I use bleach to shock. I have a feeder so I am guilty of using Trichlor (I'm not home all day due to work and have had mustard algea problems the last four seasons so I don't want to chance not having a full feeder of chlorine). How much Borax should I put in for the pH or should I just do nothing? The water is clear. This really cracked me up, there was a lady in the pool store ahead of me getting her water tested and the girl told her that she needs 20 bags of shock and a whole list of other products. I just about dropped my teeth. They are selling shock for $3.99 a bag. I did hear that her pool was the same size as mine. I only go in for something that I have to have and always tell them that I have all the chemicals I need at home. Well, sorry for the long post. I'll be waiting for a response. Penny
