We moved into our home last summer and the pool (about 15 years old) was already open and balanced. Toward the end of the summer our CYA levels were getting high... I can't remember exactly but I want to say over 140 which was concerning me.
This year we paid to have the pool opened last Tuesday since it was our first time. The pool guys opened and treated the pool initially (I think they used liquid chlorine and some sort of algicide).
The pool cleared up in about 4 days. It was slightly cloudy, but we backwashed and vacuumed and it was looking fairly good. We discovered TFP and decided to give it a try. I haven't been faithfully writing down all our testing results, but I started keeping record. I'll share what I have.
Sunday we got a CC level reading of .6, so we decided to SLAM. We figured maybe we had something in the water still brewing since we had just opened. We used the pool math calculator and added the recommended liquid bleach for FC to reach 20. I didn't realize we needed to hold the pool at shock level, so I'm not sure how long it was at 20. Monday afternoon the FC was 12.6 and CC was <.5. Unsure what to do, we tried to raise the FC back to 20. We added the recommended bleach from PoolMath but Monday evening the FC was only at 13.5.
This morning our results were:
FC 10.8
CC .4
PH 7.3
TA 200
CYA 59 (tested a few days ago at the pool store... I got CYA level of 50 on my reading at home)
We aren't really sure if we are on the right track. I feel like the FC isn't rising as high as it should when we tried to SLAM and our TA seems too high. Overall the water looks great.. clean and clear. Side note: we'd have a TON of rain in Maryland recently. Not sure how that affects things.
We are testing with the Taylor K-2006c. I'm not sure how to proceed. Thanks for the help ?
