I decided to take a blind leap on the filter. I can find little info on the JBJ Reaction 4-Stage Canister Filter. I was intrigued by its addition of a UV lamp and wanted to see how well it works.
After getting my hands on this thing, I can say it looks a like a dandy canister filter. This thing is huge.
Provided that the pump is worth a hoot (still not tested), this looks like a solid canister filter. However, I have serious doubts about its UV sterilization capabilities. It seems the lamp is too small and the flow will be too fast to do much of anything....we shall see.
