So after years of going back and forth on what to do for a sump, I've finally got it down to two choices. So what do you guys think ? Should I go with a 36"x18"x18" 50gallon or a 48"x12"18" 50gallon long. I'm leaning towards the 50 gallon long myself. Either way the sump will be 50 gallons, I just can't decide on the length. So for everyone with a sump whats better, longer or wider ??
