Which powerhead?

[Nick A]

What do you guys think would be best for my 240? I'm thinking of modding my two mj800's OR getting either a couple of Seio super flow M1100's @ 1100gph or Hydor Koralia 4's @ 1200gph.

What are other circulation options do you guys think is possible? I don't think I want to drill my tank in order to do a CL...unless I can get a much more efficient pump than running powerheads.

mj mod they great for flow. it beats my seio 2600 anyday.

mj mods for super good flow. although I have not tried the koralias, they seem nice and energy effecient as well as if they fall off the glass they stop spinning, not so for the mj mod.

Hmm....the Koralias do look like they have some good features. I'd like to try the mods, but I wouldn't really trust myself on doing it perfectly...lol
