Hi. I have a Fluval U2 in my 10g now. I think it's meant to be used in up to 30g tanks. I have a 10. So, I would like to figure out how I can reduce the outflow. I thought of not using the bio-media and putting more sponge material in the middle. Would that do anything?
I appreciate any help you can give me. Thanks.
