Small green thing

We got us a blow up pool this weekend. It says to empty it daily due to health reasons and mosquitoes. We have decided to do it every few days, depending on how dirty it gets. We are going to get a tarp to cover it with since we have all those trees dropping cones and needles. That will hopefully allow us to empty it even less often. But, my little green idea when I emptied it today was to scoop the water out and use it to water all my plants! Now I don't feel so guilty about the pool.
