Customer Reviews

Very happy, load with 4-5 pucks and don't check pool chlorine for about 2 weeks.

Easy to plumb in, get a couple threaded X barbed fittings to put it onto your return line and some for the check valve if you don’t have one already, and chlorine maintenance becomes as easy as turning a dial.
