so i'm in the market for a new water pump. i was looking on marinedepot.com and saw that the little giants have an "x" version of each of their pumps that flows a great deal more than the "non-x" version for only like 3 bucks more. does anyone know the differences besides the outlet size? i was looking at the 4MDWX-SC

MDQ recommended for pressure setups (i.e. in-line pressure filters).
MDQX recommended for free flow setups (i.e. direct return, wet/drys).

If it flows more then it uses a different impeller and uses more power within the same chassis. More power usage is the key to its operation.
