Thank you for the compliment!Love your tank! I was wondering about the difference between an AIO and a tank with a sump. My understanding is that an AIO usually has a built in sump but I'm guessing I'm wrong??
Well... "Built in sump" is a bit generous... It's more like you take the back 4" of the tank and devote it to an overflow chamber with multiple place to put heaters, return pumps and other misc equipment. Everythign is contained in the single box which keeps things a bit more simple. Having said that, I wish I went witha sump as it give you more flexibility in the long run.
