Hey Guys, I have a bunch of sand in the bottom of my tank that is causing the flow to be almost non existent. I crawled in the tank to try to shovel out some of the sand but it is sliding right off of the shovel because there is about 100 gallons of sealer left in the tank. My question is what does everyobe else do to fix the issue??? I thought about adding water and emptying into 55 gallon drums and starting from scratch. I don't want to waste the sealer but i feel this may be my only option. Any suggestions???
