Most users not only keep them up for days at a time, but they keep them running all summer. If this sounds appealing to you, there are some things that you need to keep in mind to ensure that you don’t shorten its lifespan.

The tarp will not only keep debris and bugs out of the water, but it will also keep thirsty critters with a sharp claw from taking a midnight swim and poking holes all along the sides.
