Im kicking around getting a rubbermaid 300 gal water trough and keeping some bait in it (fatheads/shiners). What i was thinking of to run an air pump all the time and then hooking up an extra battery/solar cell to my bilge pump with some sort of filter box and running that 2-3 hours a day. Any ideas or suggestions on the filter would be appreciated. Also with minimal filtration how many fish would be max?
