I have a 75 gallon and would like to add a sump to increase my bioload. What is the smallest sump available? My stand only has two cabinets. The sump could be tall, just not super wide or long. Any suggestions?
Well, you could get creative and use a hexagon shaped tank as they are taller than they are wide.
Technically you could use a teacup as your sump but it's not going to help offset your bioload! Remember, bigger is better.
