New to this can you help?

Hello
FC 8ppm
TC .25
PH 8 to 8.2
ALK 50
CYA 20 to 30ppm
CA 90ppm (I tested this because I will be adding a heater)

Could someone let me know how the test looks?
Thanks
Ron

Ron,

Something is awry with the chlorine numbers you've posted. Free Chlorine plus Combined Chlorine always equals Total Chlorine (FC+CC=TC). PH is High, should be around 7.5. Your ALk is a little low, should be between 80 and 120 ppm.
Be sure to re-test the CYA in a week since you just added some as it takes a while to dissolve. Do not add any more and I wouldn't use and more "shock", unless it's cal-hypo. Most "shocks" are dichlor which has CYA in them. That's the primary reason we all use bleach as our source of chlorine.
Based on the 15x30 dimensions you gave me and ASSUMING your pool is 4' deep (13,500 gallons), I come up with the following, to correct your numbers:
Add 5 lbs of Baking Soda to raise your ALK to around 80 (this will also raise your PH a little more).
After about a half an hour, add 20 oz of muratic acid. Wait an hour or so and re test PH. 10 oz. of muratic acid will lower your PH .2 ppm and it will probably take another 20 oz. or so but it is always best to slowly adjust to avoid over shooting. Add all of this directly to the pool in front of a return with the pump running. Be sure to look around the forum, paying close attention to the "sticky's" at the top of each section.
