Biggest tank without a sump?

[Tarolisol]

Just wondering what everyone thinks the biggest tank without a sump could be run properly? Take into account a hang on back refuge. and stuff.

I would think that "the bigger the better" would apply even more to a sumpless system.

ya but then you run into problems with skimming with a hangon - unless you would classify a external skimmer as a means to skim but then i think your defeating the purpuse of this question. And Secondly WHY ??? would you even want to do that ??? lol i have a hard enough time with my 44g b/c it has no sump

The skimming could be handled by more then 1 skimmer, low fish load and/or a hangon refugium.

I'm not a big fan of sumps, if my sump had to sit in my cabinet under my tank I wouldn't have one

Well my main reason is i want to keep some corals i cant keep in my other tank due to a regal angel(zoas). The tank is going to be in my bedroom and I cant take the noise of an overflow. I was thinking around 35-50g with a low fish load. Im used to my huge tank so have gotten used to doing it big.

My 90 gallon reef was sumpless for almost a year with no problems. I had about 140 pounds of live rock, DSB, and a aqua C remora pro hang on skimmer for filtration. I also did small weekely water changes. I just added a 30 gallon refugium about 3 months ago, and I didnt notice any changes (only the fact that my manderin will have more stuff to eat). Just remember that somethings may work for others but will not necessarily work for you. My cousin had a 70 gallon sumpless tank and for some reason any fish he put in there would die, but corals would live.

Here's a picture of my 55g tank, It went for a year with only 1 tunze 6060, a heater and the lights.

Funny you mentioned that,I had the same problem for about 2 yrs before I had a sump.Couldn't figure out what it was at the time.I was also running skimmerless on that tank,now Im thinking lack of o2 had something to do with it.

None of the reefs we've kept over the years have had sumps. That includes a2.5g, 7g, 10g, 28g, 33g, 37g, 44g, 67g, 75g, 180g, and our current 120g. The only tanks that ever had skimmers (HOB) were the 75g and 180g, but that was years ago. We stopped using skimmers because they overflowed from time to time

The key to sumpless success, in our case, is having a low bioload, lots of LR, lots of non-invasive macroalgae in the tank, and a BB so we can siphon out all the crud on a weekly basis.
