My vote for EASY maintenance is a hang on back filter. Wet/drys are nice since the bio filtration is low maintenance. If youre talking mechanical filtration though, my thought is that if you arent cleaning it, it must not be getting dirty. If mech filt. isnt getting dirty, it probably isnt doing much. My opinion for overall performance and ease would be a wet/dry with a filter sock, but those socks can get dirty really quickly
Lol..... Dane was just referring to a coffee can = 10G or Swimming pool = 220G.... It's hard to tell you what filter to use unless we know what size tank it is.... If you have a 220G you certainly wouldn't want to use a small 10G hang on the back....
Ummm i have 6 exos in a 29 gal, 11 guppies in a 10, a jag and 2 senegals in a 10, a gt, tiger pike, jd, a pleco, and crayfish in a 55. All the cichlids are juvies. I have an adult oscar in a 30...im trying to get rid of it. My Exo tank and guppy tank doesnt have a filter yet, just an air stone. Just trying to find out how to make a cheap, efficient filter w/o buying more filters.
This, it would take a little more work to set up properly but once it's running it would be the easiest way to maintain them all, plus if you do it right it can be easy to add more to the setup
