depends on how much room you have there are some better rollermats out there. I skipped the klirs because of reviews and the snags when changing the rolls but it fits in most sumps. I run a theiling and bubble magus now. pros and cons of all of them. I like the theiling for it is all enclosed and doesn't have to be in the sump. I like the bubble magus for the price but takes sump room and has to be in it.
