Help finding a larger ATO reservoir

[davidin513]

Greetings fellow reefers... I'm about a little over a month into my first 120gal tank... I currently have an apex auto top off and a 5 gallon ATO reservoir, and I've found it tends to get me somewhere between 2-3 days before I have to refill I'd like to go larger. I'd be very happy if I could get a 10 or 12 gallon reservoir inside my stand, but all of the options I've seen to date have a 10" minimum width, and I only have 9.75" available inside my stand. Does anyone have or can anyone recommend a good ATO reservoir that is only 9.75" wide and not 10?
