Yup...same with the peristaltic pumps. You push tank water INTO the Ca reactor, and you push RODI water INTO the Kalk reactor. Surprisingly, the FW seems to be harder on the pump tubing than the SW. The SW forms a thin slime layer inside the tubing which reduces wear. I'm switching from norprene tubes to silicon tubes to see how they wear.
Right now, I have to change the peristaltic tubes every 6 months or so.

Well, here is what I am using. Project is not complete yet but, I have a Masterflex peristaltic pump head purchased off Ebay for about $25.00, included a mounting bracket. These heads are very reliable and long lasting.
Coded a PIC 18F1330 for the control portion of the project including a LCD display. It is adjustable from 1ml to 120ml a min. The PIC outputs a square wave to a L297/L298 stepper driver to a PowerMax II stepper motor I had on hand. This stepper, via a 1/4" coupling turns the Masterflex peristaltic pump head. Has been running flawlessly for the last 3 months sitting in it's breadboard form. Part 2 of the project will be controlling the CO2 from the regulator to the calcium reactor using a Clippard electronic valve. http://www.clippard.com/store/displa...?sku=EV-2-12-L This should make dialing in the reactor much easier. Finally will put the whole thing on a PCB and in a appropriate enclosure
