nutria

IG plaster pools built in 1985 (?): 16k(?) gallons lap pool (62'x8') connected by a spillover to 17k(?) gallons squarish pool (22.5'x18'). DE filters Pentair NS-48(x2), polaris 280 (non-functioning). Inline chlorinator [removed!] -> Circupool Si60 SWCG [Newly self installed March 2016!]. Recently acquired dolphin nautilus+ [Summer 2015]. Still figuring out what else I have and how things work.
