That is a good point!
I won't claim to know the physics behind it, but the directions are VERY accurate, give or take a 1/4 inch here or there.
FIRST of all we need to differentiate between the 65 and the bigger models. The 65 is the only model with the valve on the pump and I have no experience with it.
It IS possible to sink the pump just slightly less than the recommended 3 inches. It takes about 1/4" more depth to be able to turn the pump intake away from bubble diffuser and not have the pump housing interfere with the box.
The diffuser box top HAS to be perfectly parallel with your water level. There is no adjustment for that, so you have to place something between the bottom of the box and your glass as a wedge to force the low side of the box to be even with the high side.
