Thanks Richard

Yeah I have same issue with the one sock getting dirtier than the other. I can't put the tee in the centre of them with the position of my 2" return. When the first ones dirty I swap them and when they are both dirty clean them both. 7-10 days sounds about the same as mine.

How are you cleaning yours? I've been putting mine in a front load washer on the sanitize cycle (no soap) and it's been working pretty well.

I sure like how they eliminate any bubbles in the sump.
