I have the same cell as you. It always reads about 200-300ppm lower than the test strips I use read. Leslie's always told me my salt was even higher than my strips. They use an electronic sensor test. As long as you know your salt level and your system isn't shutting off due to low salt, don't...

I have been adding bleach since water is too cold for SWG to work. I haven't added this week yet. So I expected it to be low. I am glad to know why the CH and TA have gone up. That was confusing since I haven't added or lost water. So if I continue to keep CSI low to clean up scale, will I end...

I have been testing every two weeks over the winter. I have been maintaining a CSI of -.6 to -.8 trying to burn off a white scale from my rocks and tile and black streaking marks on my plaster from two years of my pool guy keeping PH at 8.2+. There has been a slight improvement in the tile but...

Hi. I have been working on lowering my TA for over a week now. I added acid and dropped the PH to 7.0. I am running my waterfall and ran a garden hose from my rain drain to a sprinkler head hung over the wall to make bubbles. It takes about three days for the PH to raise back up to 7.6. I have...

I did plug SWG back in and hung two socks with CYA. Re-tested water and the numbers are: FC 9.5 CC. Less than .5 (barely pInk) TA 140 CH 310 CYA 50 PH 8.2 (between 8.0-8.2) Salt 3310 Do I wait for CYA to disolve and mix before I try and lower PH? I was getting ready to add acid to lower PH so...

My target was 75. I'm am at 40 now. I get 4lb and 1 oz with the calculator. I bought a 4 lb jug. Was going to use all of it. Should end up around 74. And lower my ph by .63 to a level I don't know because I haven't tested PH because it is not accurate with FC above 10ppm. How did I do?

Ok. I'm getting done. I found out that there was a difference between my test and my Son's. He was stingy with powder and was so slow with drops that they were a little small. I had him do a test right next to me and our numbers were off. After dark last night I got a FC of 16.5. This morning...

It has been unplugged since I started the shock process. Someone told me to do that way back in the beginning. I checked my FC level at 6:00pm and it fell to 10.5. So it dropped 9ppm in 6 1/2 hours of full sunlight. Given that my CYA is still only 40, does that sound right?

Well, the blueprints for the pool say 13,900 gal. The builder says they doug it a little deeper. I know I had them stretch one end out a little wider than planned and it is about 6" deeper in the bottom then planned. I always figured about 15,000 gal. I don't know for sure. The salt I added...

I did test in the evening, I just didn't test earlier that day after adding the chlorine to raise the level back up. I can only assume what the peak was earlier that day based on what the calculator said it would do. Today, one hour after adding the gal of 10% chlrorine the FC is at 19.5 and CC...

The sun was coming up but not hitting the pool yet. Yesterday, I used calculator to see what effect adding the remaining amount of bleach I had left was. It was 16.6. I added it and then tested later that night and still had 16.5. Never actually tested to see the 16.6. Jut assumed the calculator...

Ok. I retested with a large scoop and still got 10.0. I guess I'm not done yet. ???

The scoop issue could be the problem. My son did the test last night. I'll retest with a larger scoop and repost the result. Thanks.

I'm confused again. I continued to test FC yesterday. It fell to 13 so I adjusted it to 16.6 (the amount of bleach I had left)around noon. At 10:30pm it remained at 16.5. I had added 4 bags of solar salt around 3pm. I tested FC this morning at 7am before sun hit the pool and it dropped to 10.5...

Thank you Jason.
