Thanks for the reply and info, what’s the concern that my SWCG only produced .6 FC over night? Is it supposed to increase more FC when the suns not out? I was under the impression the SWCG was more to maintain my FC levels. Again thank you and really appreciate the guidance.Overnight, there's no sun to consume FC. If you didn't have a SWG running, and tested after sunset and again before sunrise, your should have essentially zero FC loss. I'm concerned that yours only went up 0.6.
Speaking of 0.6, that tells me you're using a 25 mL sample size. Using a 10 mL sample is fine, and uses significantly less reagents. Pools don't need the 0.2 level of precision that 25 mL sampling provides.
Anywhere between target and SLAM level on the FC/CYA chart is safe for both your pool and your kids to swim in. Especially while getting your SWG dialed in, it's best not to be too close to the bottom of target, nor SLAM level, since we aren't sure what your pool is going to do yet.
Keep testing and reporting your results. We'll get it dialed in and you'll know what to expect in short order.
