OK, my 850s went fast. Let's see how the 250s do. I have 3 available. One is a version 2 and the other two are version 1s but have been updated with all version 2 parts, so all are identical other than the label. All are in great condition. Each will be set up as shown, including new unused pipe sets and fresh foam in 2 deep trays, the top tray, and the prefilter. You'll just need new tubing and whatever you want in the other tray.
3 available at $125 each plus shipping. Shipping will be about $22-$34.
