Any of them use 5/8" hoses by any chance. I can look but thought I ask just in case someone researched this already. It'd be easier to switch back and forth since I already have a 5/8" setup going on both sides of my tank.
I already have a review of the Odyssea CFS500 here, and there are a few mods to it as well. They too have been around for about a yearish.
