i used the self leveling cement in my basement. First i nailed two by fours to create a rectangle larger than my stand then i used duct tape to seal all the wood to the floor. since i needed about three inches or more of concrete i used 1 bag of quick crete and 4 buckets of the self leveling concrete. its not really that hard its just a lil messy and and takes some time to feather the first layer of concrete. My 7 foot tank has been running over 6 months now and is almost complete level on all four corners.
