Cobalt Aquatics Aqua Sponge Aquarium Cleaning Mat, XX-Large

So I have tried several of these rugs, both the ones made specifically for cleaning aquariums and others marketed for wet situations, and these Cobalt rugs are simply not worth the money. They absorb about as much as a regular bath towel, but the water stays close to the surface and will run off when you attempt to pick up the rug. It needs to be hung up by two corners to dry completely. It does not dry efficiently just hanging it over a rod in the shower or by laying flat. Funny, but chewy sells a dog drying water grabber towel that actually performs better than this thing.
