I have a metal water tank in my shop (approximately 160 gallon) that I used as a rinse tank. I have a 1/2 hp sump pump I placed on it to run 12 1/2" shower heads. I built an outlet too so the excess water can run out to prevent over pressure on the sump pump.
My question is, will this set up be too powerful if I were to convert it to a live well? I My thought was I'd place a grate near the sump pump to prevent the fish from getting too close to it. I'd also clean the tank really well before using it.
It should work for short term storage. Use well water (chlorinated water will kill the fish) and you might have to put some defoamer pentairaes.com/proliner-defoamer.html in the tank if you see a lot of foam showing up on the waters surface. I have heard of guys using powdered coffee creamer in a pinch.
Keep them cool, and oxygen in the water and they would live for quite awhile.
That's the plan. But, I was wondering if I would be introducing too much oxygen into the water. It's actually a 170 gallon tank. I obviously wouldn't be filling it full. Probably not even half full. I know a cooler might be the easier route but, I don't have a cooler and was just looking to use something I already have rather than buy anything.
You are well equipped to keep them alive for a week. I would use that to keep bait on hand vs a live well in your garage. Just add a bio active treatment to get rid of the ammonia and do weekly water replacement/cleaning
FWIW, 50# of Golden Shiners will stay alive in a 190 gal tank for a day using pure O2 but after 2 days they will be piping at the surface. Changed the water and they stopped piping. O2 levels were 10 mg/l, water temp 65°F. They were purged for 3 days before I picked them up.
