Oh really??!? seems to me, if you shim the side of the tank with the lowest water level, you'd be making it LOWER... and that would be making it worse for level...TwistedPenguin;3466010; said:You do realize that you put the cardboard/shim under the end of the tank that has the lowest level of water, right?
If you raise the high water side, it will equal out to the low water side...
