Hello. I need some help to understand if my SWG is working correctly. My FC and TC are decreasing constantly to the point I have to shock the pool almost daily to increase ORP. I run the pool at 88F and the chemistry otherwise is perfect. I use pool clarifiers weekly, enzyme and phosphate removers and the water is beautifully clear. My issue is that I have to maintain it daily and I'm not getting any value from my SWG. The brand is Pentair intellichlor. It has been replaced almost yearly by my pool contractor and it's a newer system as the pool is only on its third season. The salt level is at 3400ppm and I run it with an intellichem that keeps a nice ph balance. Filters and flow are perfect. I run the pump 24 hours a day. I checked my FC and TC right after the SWG and I only get 0.5 FC and 1TC. It's running at 100%. In my perception this is the problem. If I'm trying to get to 5-5 FC-TC I assume I shall get those readiness right at the SWG. So here are my questions.
1. What are the FC and TC values expected out of SWG treated flow?
2. What is the typical percentage range they shall be running? Mine is 100%
3. Do you have other tips or recommendations?
I have a 15-18k gals gunite inground pool. I'm In MI. I'm expecting the contractor to open my chlorinator this week and see if it needs cleaning but I gave up on this brand as it has been replaced yearly since the first season
Thank you for your feedback.
