So I am starting to gather supplies to my my 750 Gallon Frontosa tank. The fish are currently in a 125g (6 foot tank). My plan is to use either the 125 gallon or another 120 gallon (4 foot) tank as the sump for the 750. With the 2 tanks having similar volume, what are the pros and cons of a longer narrow sump vs a shorter wider sump. I plan on doing a wet sump with filter socks and most likely a refugium to double as a fry tank if the frontosa spawn. Thoughts??
