So, I am thinking of a small upgrade. With the $1 per gallon sale at Petco I have been thinking of going to a 40b. Now, I know what you're thinking. 40b isn't much of an upgrade over a 30g. Well, my 30g is an AIO so I am losing at least 5 gallons with the back chamber. Plus, throw in the room I will be saving with a sump and all and I figure it's almost double what I have. Anyway, I wanted to do a glass-holes overflow and I wanted to know what you guys thought. Would the 700gph be OK? 700 seems like it's just barely enough but 1500gph seems like way too much. So, what does everyone think?
