Hi everyone,
First thanks TFP members for all your precious comments/suggestions. I was running my pool only with those "awful" pucks for the last few years. Now I've found TFP and I made the switch to liquid chlorine instead. I do the daily checks for FC and PH and during the weekends I do the full check FC,CC,CYA and TA. Of course, I vaccuum and add water if need be. My tap water is very hard and is also considered alkaline. I alway use tap water to fill or top my pool up. My current TA is 200. pH this morning was about 7.6-7.7. CYA was 40 three weeks ago but we got a lot of hot and sunny days followed by some heavy rain days. CYA is now around 30. I'm assuming CYA is now lower because of rain water and/or tap water I added. I add on average 1.2L of liquid chlorine per day to keep a FC of about 5. Is that quantity normal ? My CYA was 40 so according to the FC/CYA chart my FC level should between 5-7 with a minimum of 3. Now my CYA has dropped to 30, FC level should be between 4-6 with a minimum of 2.
Here are my questions:
1) Should I try to bring my TA down from 200 to then recommended level of 50-90 ? That means adding muriatic acid so my pH goes from 7.6-7.7 to 7.2. In my case, I would need to add 0.6 liters of muriatic acid. That being said TA would only be lowered by 5.8 according to the Pool Math app. Going from TA 200 -> 100 would require me to do that process 17-18 times to reach an "acceptable" level. However, I would need to aerate my pool to bring my pH up to 7.6 before adding more acid. Does that make sense to you guys ?
2) Should I try to bring up my CYA from 30 to 40 or even 50 so my daily FC loss is less than the average 2ppm ? I have a solar cover on most of the time unless it is super hot.
Thanks again,
René
