After a year of first-time pool ownership, I'm doing really well on the water maintenance but I'm still learning how to take care of my equipment. I have this piece of equipment that looks to me like a filter (perhaps for the refill water?) but I'm not sure. More importantly, what sort of regular maintenance does it need, if any? It's pretty well strapped to the side of the pool. I haven't tracked down where the pipes go yet.
Thanks as always
