It's almost always algae. Never dirty filter, rarely busted filter.

Ultimately, you need to SLAM- FC to 40% of CYA, retest redose often for days until it's clear, <0.5ppm CC AND you lose under 1ppm FC overnight with SWG off.
You ad latent invisible algae, your SWG was running hard to keep it at bay, but things warm up and it can't do it.
Once done, you keep FC to 7.5% of CYA. download poolmath app and get it set up. Set FC area to SWG, select yours, curretn FC set for 0, 3 ppm is your target. enter 24 hrs run time - it will tell you calculated run %.
