Originally made by Pete ("Off the Reef"??). Dual chamber, about 18" high. Several years old, but in good condition. Includes ARM media in both chambers. Regulator & pH probe are brand new - less than a month of use before I decided to go SPS - less. pH probe was "pickled" in RO/DI and not left to dry. Pump is a Mag 5, and is set up to go in the sump - it had a tiny leak that was repaired/rigged, and may need to be replaced at some point. I just don't trust it external. I have NOT cleaned it up - obviously - but since someone was interested, I decided to post it. Comes with 2 small bottles, one empty, the other with some CO2 in it (last time I checked). I also have a couple of 20# bottles, if interested.

$225.
