I no longer will have use for this unit. It is a MyReef Creations Dual Nano Reactor in use since September '03. It is in perfect condition, and I even have two new extra 3/8" covers that will be included-the 1/4" originally supplied are working just fine.
You can find more info on the reactor here at Andy's website:
http://www.myreefcreations.com/main.html (then calcium reactors on the navigation bar)
Size recommendations are not provided but for reference the dual nano holds 6# media and his standard size single chamber reactor-rated for 300g tanks-holds 7#. These size recommendations are very arbitrary however and a direct comparison between dual and single chamber designs can't really be made (as the second chamber typically only "mops up" excess CO2 thereby raising pH, Ca 2+ and CO3 2- but less so than the first chamber). A small reactor can meet the demands of a large system but with more frequent replacement of media and increased CO2 injection. Realistically this reactor is probably best-suited for a 75 or similar volume tank.
I purchased the unit new from Andy with his CO2 package (Blueline Regulator/solenoid/needle valve-all one unit) and mag 2
recirc pump. To feed the reactor i will include a minijet 606-which works great. Purchased new everything was $330 (plus minjet, ARM media, flex vinyl hose and other lil things you won't need to purchase). I believe his price has gone up some since then too.
I will accept offers for the reactor alone (with both pumps-all you would need is CO2 regulator and CO2 bottle)
OR the reactor+CO2 regulator unit (all you would need is CO2 bottle).
I'd love for it to find a good local home and i'm thinking $250 OBO including the reg would be reasonable. Obviously less without the CO2 Regulator unit. Here's a pick and links to a couple threads with picks

EDIT-not the sump-the reactors on the LEFT!
