Milwaukee SMS-122 pH & reversed pH controllers
I have 1 each of the SMS-122 and SMS-122 Reversed controller for sale, now that I've upgraded to a Lighthouse PRO. Both are used and in excellant condition, and I'm asking $85 each shipped.
We all know what a regular pH controller does, but the reversed is designed to turn OFF a device when a high set point is reached. I have always used this for Kalk dosing my reef system, and have had it set to kill my Kalk reactor if the pH reached 8.5.
I don't have an established track record here, but I'm very well known on RC, and in a positive way too.
