Five years ago we moved into a house with an older inground pool and spa. I love it but every year it seems there is always a period where its either green or something is really out of whack and the surface will one day have to be redone. Just got the water crystal clear again last week and kids are loving the pool during this "staying home more" period. We have a tablet feeder, but have been using liquid chlorine as of late and found and article related SLAMming your pool and living the trouble free pool life. Hoping to figure out the right combination for keeping pool balanced and clear. Looking forward to learning more about pools.
