Wow, that looks very cool. Obviously, I would think a large return pump would be needed but that investment might ultimatly be a cheaper alternative than 3 PHs and a return.
well then i think i'll go ahead and stay with a scwd on my return and a scwd on a closed loop.but i still say that thing looks awesome and would really like to hear from someone that has one running.thanks for the link though.are you thinking about getting one?
Always am skeptical of new products until proven their efficiency through experience by other hobbyists who have used them. Needs time to prove their value! Looks great though and thanks for the link!
