Last summer was my first year as a pool owner. Thanks to this wonderful page, I was able to keep my pool sparkling all summer so I am hoping for some new advice to get me started for this season. So, I didn’t close the pool properly (pretty much once summer was over I never messed with it) I went out to it the other day and the water was almost black with LOTS of algae 😱 my own fault, I know. What steps should I take now? The usual SLAM process? Should I drain and refill?
My pool is a 22x52 Coleman Power Steel. I just replaced the cartridge filter it came with to a sand filter.
