This is my first year with the SWG, I have to say, i don't know how I lived without it. That and adding a robot have been life changing. I don't have time to keep up with manually adding bleach every day or two. It has made my life 100% easier than last year when i was battling algae from laziness of staying on top of bleach. My TA was 90 and i was having issues with the PH spiking up in the 8's, so i lowered PH to 7, and it dropped my TA (not sure how much, i should probably check) and PH has stayed steady around 7.6 ever since, and that was 3 weeks ago.
Im beyond happy with my decision to switch, my pool is about the same size as yours, a tiny bit bigger. i don't have any crazy automation, i just put my rj30 on a timer, and its set to go on 30 minutes after the pump starts, and turn off 30 minutes before the pump turns off. My pool is shaded in the afternoon, so i run my pump for 10 hours at 1500rpm, and have the rj30 set at 30-35%.
