I have a 55 gallon drum with a small aerator. The problem is, the water gets dirty in just a few days. What would be a good filter for the tank which probably only has 10-15 gallons of water in it? Any suggestions on aerators too? Would like to have about 20 gallons of water and a filter/aerator to keep my minnows alive. Also, what is good feed for them? Most are creek chubs/minnows.
Thanks
Bassky
