i just took a quick measurement it looks like i could get a 10g in there. i measured the 10g in my kids room and its only 10" wide and 20" long if i remember right. i have a 20g long laying around too but i think its too wide. tomorrow ill clean out the stand and see if it fits but i doubt it. sorry for all the questions ive been reading alot but this is still very new to me. i really appreciate the help,thanks, Mike
Never be sorry about asking questions. Asking questions is how you learn and the members here are happy to answer your questions. Even a ten gallon tank as a sump can make a huge difference even if you just put one baffle and a skimmer in it with the return pump. Google sump setups and look at the images so you can get an idea of the elaborate sump setups that people have. I myself plumbed everything to the basement. I have a 90g fuge a 100g stock tank and a 40g breeder that runs off the stock tank. But I also had a 125g display with a heavy bio load so it was needed.
