MP40s won’t push 6 feet. If it were me I would 2 Jecod CP-55 vertically blowing down the 2 side walls, those will move the whole tank. You can add from there though you may want to drill for some closed loops. You also going to have to be careful of any sps growth that starts to grow into the path of water, those pumps will blow flesh off of anything within a foot.
