eheim is looking on the brighter side for me I figured that but wanted opinions! I have 3 mags mag 7, mag 5 , and mag 12. I'm completly magged out it wasnt in my interest but it just happened that way but im noticing the sound is starting to P*** me off! It looks like im gonna need to post these guys for sale or trade for eheims! I also updated my koralias for maxi jet 1200's with the mods a set of them! I like them alot but i think i didnt read up on them as good cuz obvously i need the magnet for them cuz there LOUD and serously overkill in my mixed reef 54g! I'm thinking about selling the mj 1200's with kits and getting another k 3. I had 2 k 3 but one broke maybe i should get another and that will do it for me. Any suggestions on what pump size i should get for eheims? I'm looking in the 700gph range for the 54g, 1200gph for the 41g, and somewhere around 700gph for my aqua c urchin?
