It's an older model, from Aquatic Systems Design, and uses an Eheim recirculation pump that's dead silent. ASD is out of business now but fortunately they used standard plumbing on everything. I bought the reactor and redid all of the plumbing fresh.
There was a small crack in the lid, but it's been repaired and DOES NOT leak. It's been running on my tank for a couple of weeks. It can be fed via 1/4 or 1/2 inch lines. This reactor is nearly a clone of a Geo 618. 6 inch wide chamber, 18 inches tall.
Just yesterday I added a second chamber and put new plates into it. Unfortunately when I got it home I realized that the reactor with the second chamber and my CO2 tank takes up more space than I have so my project is selling stuff to buy a reactor with a smaller footprint.
Looking for $300 SHIPPED for the reactor with pump and second chamber. I also purchased a new pH probe holder because I wanted one that would allow the probe to sit deeper in the chamber. I'll include it and you can install it if you'd like.
Ignore the wiring mess please!
