I just opened my pool on Sunday, it was gross and black. I vacuumed a lot out until it got dark outside and couldn't really see what I was doing anymore. I've been scrubbing and back washing since then I did pour a couple gallons of chlorine in (after checking pool math since FC was very low) and enough salt to get up to/little past the recommended salt level.
I checked the levels Wednesday night and adjusted them right away once I found out FC was only 2 ppm and CYA was 0! I should've checked the pool levels last night but got too tired, I did dump a gallon of 12% chlorine in to hold it over till I had more time to check everything after work today.
Sorry, I know this doesnt help but the levels are probably about (didn't have time to check before work this morning):
So onto my main question, should my SWG be doing this? Or should I not even use it while SLAMing, I was hoping I could use it to bump up/maintain my FC level during the day? I turned it on before I left for work this morning and my girlfriend called me to tell me it looked bubbly. I had her turn off the SWG. This is my 3rd season with the pool, i've never seen it really do that. I've never cleaned the SWG
Here it is now:
