reactor----in the sump or out?

[christyf5]

I used to run both on the outside until I lost the O ring for one. I didn't have much room in my old sump to have them on the inside. Now that I have a larger sump I run them both in the sump. Kind of sucks as they grow all sorts of crap on them but the one is the phosban 550 which has a crap design IMO. I do hang my carbon one (with o ring) on the inside of the sump (still in the water though) but the 550 just sits in the sump itself.
