Biggest tank without a sump?

[fresh]

You can do a very nice tank without a sump up to probably 150gal. Keep in mind that your bio-load has to be low, lots of live rock, and good skimming and water movement are always a plus.

I have a 72gal sumpless that has been very successful for about a year now. I even keep SPS corals and clams!!! It just depends on what you want to do, and what you are willing to sacrifice.

I only have 2 clowns, 2 chromis and a yellow tang in there. I also have over 100lbs of liverock and a remora-pro for a skimmer.

Well its good to hear all these comments, i was concerened with a 30-50g. I had bad algea in my first tank years ago which was 77 sumpless. But with more knowledge now I'm sure ill have no problem with this size.
