I have a 44gal brute trash can with wheels and a 1/3 hp Utilitech submersible pump. This thing is a life saver. It pumps more GPH
then my faucet and will drain a tank in minutes. I add the pump into the tank and place the hose end in the trash can and turn it on the drain the trash can and replace the water in the can dechlorinate it and add it back to the tank. Best money I ever spent. Cost a few hundred for everything but if you have MTS Multiple Tank Syndrome this is a must. The python waste good water to run and that adds up. So if you have MTS goto the store and get this setup it will save the life of your fish. By making water changes effort less.
