i would say a 40b thats what i have under my 120g works fine enough space.
+ 1 on the 40b not fitting well in a 125g stand if it is a 18" wide tank. The 40b is also 18" wide and with the inside support of the stand it will not fit. The 33g i believe is 12" wide that would work pretty good. A 55g sump would probably be to tall in your stand. Which will make it very hard to install or remove anything in the sump once it is installed under your stand if that is were your sump will be.
