Great job on the testing. You will get more confident as you continue to test every other day or so.Opinions,suggestions. Now what i still dont ge it is the 26 FC if is good or bad? I think was mess up my water was the clorox xtrablue tablets and the clorox shock. As long i only use chlorine or leslies tablets during summer. Next im planning go into the swg way.
Remember that your CYA is in decade numbers - 30, 40, 50 etc. You cannot interpret the in between lines as it is a log arithmetic scale. So according to the FC/CYA Levels at CYA of 40 your FC should target between 5-7ppm. So just let your FC level come down over time but I would still test every 2nd day or so.
Also, did you download the PoolMath app? Once you set it up for your pool and you input your test results, it will provide you the recommended levels and guide you on adjustments. It is a great way to track your progress. Also, as you use different strengths of bleach or tablets, you can see the potential effect of those. Well worth the $8 annual cost.
Obviously, you can still come to the forum and request help such as what @kimkats has provided to you as what to do first and what to focus on now but the app will help you see how those recommendations affect your pool chemistry.
