As long as your rocks are stable , dont let it collapse or topple, should be no problem, how deep is ur 4ft? If more than 18" I suggest you go for 10mm thickness else the Head pressure from the depth might crack your tank in the long run.

My thank is 4x1.5x1.5 and thikness is 6 or 8mm. I don't lean rocks on the sides, I left 1 to 2" distnace at the back. I just make sure the pile up is stable.

I find it helps with water circulation, but I loose the space in the swimming area at the front
