Has anyone had a chlorine puck last for months and months??? I put one in a feeder in my pool late last fall to help maintain the Cl level since my filter and SWG wouldn't be running so often. Last weekend I opened up the floater and saw that MAYBE about 1/2 the puck has dissolved.

Is it just because the water got colder? The lowest it got over the winter was 50 degrees, and now it's up to 68 degrees.

Seems very weird to me, that's all. Happily, I got to look at a pretty blue pool all winter with only minimal maintenance!
