One of the biggest problems I always run into when adding something to my tank is getting a small amount of water spilled on the floor. I am starting to just get used to it. Sure you can put a towel down, but just think of how much cooler you would be if you put a Dry Mate aquarium cleaning mat on the floor. “Super absorbent mat contains aquarium spills and prevents soak-through, perfect place to set wet aquarium dÃ©cor during routine maintenance, practical solution to wet messy floors associated with water changes.” Sure it is just an overpriced mat, but hey we want one! Check online or your local fish store for about $13.
