Tank not leveled ?

[zusima]

Not to beat a dead horse but carpet changes things a tad. Use a 3' level and check each rim or measure your water line with all pumps off. Write down each direction the tank is off in..example the left front is 1/4 lower than the front right in Pic. Check all 4 then drain to exceptable level..use carpet skids or shims that are the thickness off you wrote down. 1/4 under left leg. Don't go by the level at this point as when you refill with water the weight will compress your carpet and foam underlayment and then possibly be off again hence your measuring when full. Make sense?

And put the shims between the tank legs and carpet? Correct ?

Could you also use the levelling feet on the Red Sea to adjust later?

Here are the pics from the manual:
