I am going to be setting up what I am hoping to be a large bait tank. The primary bait in it will be Goldfish, but I may also hold Bluegills, Bullheads & Rockbass in it. I was going to go with some sort of plastic horse trough from Tractor Supply Company. I am drawing a blank as far as a filtration system goes & pump. At first, I was going to use several underwater filters that are designed to be used w/ 55 gallon aquariums & several power heads. If I did this cam anyone tell me how many power heads I would need? When I ran my old 55 gallon setup , I used 2 pretty nice power heads. I am also thinking of just getting a pump that runs about $100 from my local tackle store. I think the pumps they sell are the same pump they use to run their bait tanks for the bait they sell. The trough I am wanting should hold between 90-100 gallons of water. I am not wanting to bury it in the ground, this thing will be sitting in my garage. Can anyone help me w/ some blueprints, ideas, sites, etc...? I am not wanting to spend a fortune on this, especially with everything else that we have going on right now. If possible I want to stay under $200. This is what I was suppose to get w/ my part of our tax return. Any info you can share would be great. Also..... if anyone has a prebuilt system like this for sale, please let me know.
