The following items are brand new in box and therefore have never seen water:
Tunze Osmomat 5024. This item is dicontinued by Tunze and is designed for sumpless use. I bought it to tide me over on my little-to-big tank transition and never ended up using it. I felt it was too large for the equipment I already had in my 30g. It is roughly 5" tall, 2" deep and 4.5" long. It uses technology similar to the Osmolator Universal 3155. Do some searches and see what you think. You can have it for $130.
MRC CR-4. Sadly my transition to a big tank has lasted far longer than I had hoped. I ended up buying a more compact design that I can fit in my "30g space" and will still work when I step up to the mother. $295. Price includes 8 lbs. of ARM and spraybar.
I bought the reactor back when Andy sold them with an
Iwaki pump rather than the Mag's he typically sells now. Iwaki 20 RLT $150.
I also have a Milwaukie CO2 regulator, Milwaukie ph Controller and 5 and 10 lb CO2 bottles that I bought from Andy and would prefer to keep for my new setup but I might be willing to sell if it helps you be comfortable with making a deal.

Oh, and I live in SW Portland if you would like to swing by and take a look at the goods. PM me. I'm certainly interested in exotic frag trades as well.
