Is there any advantage to having a few fish in my sump? Its remote and it’s around 125gallons of water, houses my skimmer return pumps and a small refuge. I would need to make sure the return pumps won’t suck them up, I was wondering if there was an advantage. I have sock filters which catches a lot of the food that goes thru the over flows. Look for thoughts. Thanks. Thanks 6 plus years old.
