I have a lightly used Milwaukee SMS122 pH Controller with the probe. This was purchased at the beginning of January.

It was only used for 2 months at most. The calcium reactor was too big for my current tank needs. I have kept the probe submerged in the sump so it does not dry out.

SMS122 pH Controller w/ probe $85

BTW, I will be coming to San Antonio this Saturday to deliver some fish and a light fixture. If anyone in San Antonio (or along the way) is interested, we may be able to meet up.
