I'm looking for some suggestions on upgrading my circulation in my 75. I currently have a mag9 as my return from my sump and 3 maxi jets stuck in various corners of the tank. I would like to upgrade to something a little better, however, i dont want to shell out vortech type $$$ - I was looking at the sureflow mods for the MJ or even the tunze nanostreams...so many options out there. the koralias are nice but they are HUGE...if i do go with the sureflow mod is one enough for my 75 or do i need two? Any suggestions would be greatly appreciated.
Thanks.
Thanks.
