Hi guys and gals...
I'm opening my pool after the first winter since building the pool last summer. Everything wintered well and I'm pretty much up and running for this season!...Very excited!! I'm having a bit of confusion, however, with my test results. Before starting my SWG, I cleaned everything very well and added enough liquid chlorine to shock the pool a couple times (using pool math, of course) and have had the pump and filter working 24/7 for a few days now. The water is crystal clear and all is good...except my test results. A little more background...after I shocked the pool the first time, the FC level dropped back down to 3ppm in a couple days. I shocked it a second time 2 days ago (using enough chlorine to bring it to about 10 ppm (using pool math...I added one full 5L jug of 10.8% liquid chlorine). Now, 2 days later, my FC tests at 23 PPM. I'm totally stumped at how that could happen. I have been playing with the settings of my SWG a bit in the past couple days, however, it has not even been running most of the time.
Here is my full test results from earlier today... FC 23ppm, Ph 7.5, TA 135, CYA 35, CH 125...and my salt reading on the hayward pro logic computer is 3000, while the test strips are only showing 2600 ppm.
...First, I'm very confused over the high FC reading (although it read 34ppm after the first time I shocked it, even though I only used one 5L jug of 10.8% chlorine, but went back to normal in a couple days). Second, my TA was happy all season last year between 90-110...I'm not sure what caused the jump to 130-140 for startup this year. Third, why would my (nearly brand new) Salt cell be reading 3000ppm when the test strip only reads 2600ppm? Even though the cell looked clean, I did soak it in the acid solution and rinse really well before reinstalling. It literally only has 3 months of use.
Any feedback is greatly appreciated, as always!
Thanks!
Adam
