yes i have used peroxide just a bottle cap to 10 gallons i never measure. i always try to fill my tank in deep water. usually not where i catch my bait. i have a few places around where i fish where i fill my tank that the water temp is alot better than others.

another trick is to use a long rope on a 5 gallon bucket and get the bucket deeper than the surface to fill your tank.

anyway you do it this time of year it is tuff. there aint nuthin better than catchin stripers with big bait.

what size catfish you guys catchin? aint nuthin wrong with some big cats.
