I was wondering what the best was to set up a filter system for my 45 gallon tank with 20 gallon sump is.
What I'm currently doing is having the outbound flow go into the sump through a filter sock, into a a chamber with a protein skimmer, then through some live rock in another chamber, then through a filter pad into another chamber where the pump is. This will then be pumped back up into the show tank.
I don't really want to spend a whole bunch more money but I was just wondering if there was any key stuff I was missing. I've also been hearing a lot about carbon in the filtering process and was wondering if it was at all necessary.
Thanks
