First, that is great you are committed to resolving this. I cannot recall a time where someone started a SLAM, stuck with it, and it did not work. Some took longer than others, and a lot of patience tested, but it will work.
Your cell does appear to be under sized, and running it at 100% output, 24 hours a day gets you about 3.5 chlorine per day. In the Georgia summer, you could burn that off each day, so you will need to supplement with liquid chlorine. Using Pool Math, and assuming you need another 1ppm of chlorine per day to keep you on the higher side, you will need about a 32 ounces per day, on top of your cell output. 3.5 from the cell and 1 from the liquid gets you about 4.5 addition of chlorine per day. In the middle of summer in Georgia, you can burn off up to 5, so you will need to keep up on the testing to make sure you keep up on the demands.
In short, once you get through this, daily, or every other day once you get the hang of it, and daily chlorine doses will keep your pool in the proper sanitization range and keep the algae at bay.
Once you get through this, you follow the FC/CYA chart as you mentioned. In Georgia, in the summer, you likely want your CYA closer to 70, so looking at the chart, for a SWCG pool, your range is 3-5. You want to aim for the higher end, never towards the lower end, which is a cliff you dive off and head towards another algae outbreak. So lets say you want to be around 5 for example.what is the recommended FC to keep my pool at so that I never have to do this again? I know it depends on the CYA but the toggle on pool math says between 2 & 8. That’s a pretty big difference. Also keeping in mind that my salt cell apparently is too small for my pool so I guess I need to do stuff to compensate?
