Hello from Georgia. I am putting together a holding tank (275 gallons) to hold bream/bluegill for bait. This will be an above ground tank. It will only be used 6-7 months a year.

I have my air but I think I am going to need some sort of filtration system.I will be trying to keep 100-200 in it at a time anywhere from 4-6" in size.

Can someone suggest a simple filtration system?

Thanks,
Troy
