After seeing another members tank explode, I want to share this product.
I originally bought these for my indoor hydroponics tent.
Last week, we got a lot of rain. Flooding. My neighbors water was coming into my yard. I put one of these down and it kept the water at bay.
The ones I have are 5’ x 6” x 3.5”. It will absorb 5.28 gallons of water. Not much for most aquariums, but if put on the floor along the back walls of your fish room, they will keep water from going through your walls.
They make larger ones too.
