Protect the bladder of your tank by using our tank inversion stand. Most tanks hold the water in the top portion of the tank instead of the bottom. Storing the water on top of the bladder adds the weight of the water to the pressure to cause unnecessary stress on the bladder. By inverting (turning upside down) it removes the weight of the water on the seal where the bladder is attached to the inside of the tank. Fits most standard 3 and 4 gallon tanks.
