Wow, at that price couldn't you just slap another D5 in the loop?

For those that like to use the D5s (strong) pumps, it is less expensive, and less of a hassle, than current solutions for powering and controlling them.

a simple voltage multiplier and rheostat would do the trick, and cost a lot less than $80 and you could mount it anywhere in the case
but for d5 vario's the gains don't seem worth it you get a few psi and a few tenths of a gallon per minute according to martin's tests, i think the tubing/g1/4" might be the limiting factor now, 1/2" id tubing has an internal area of ~0.39"

on setting 5 at 24v it topped out at 4.58 gpm, that's 1057.98 cubic inches per minute through a .39" tube, the tubing itself is creating restriction at that point

This is for people that already have 2 pumps, they also have a single pump controller like this.
