Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Large HSB mortality

George,

Consider a .5% salt solution for holding HSBs to be returned to water. If 40 qt ice chest...then 10 gallons water @ 8 lbs per gallon = 80 lbs water, so .4 lbs salt...or just 1/2 lb of salt.

For oxygen, you can buy small oxygen cylinders and oxygen regulator at local gas place. Get a "Point 4" micropore diffuser from aquaticecosystems.com and regulate your oxygen flow with the regulator. One small oxygen bottle might last a very long time with this system, just keeping a few fish alive from time to time. These micropore diffusers are worth the investment, because they'll save you trips to refill the oxygen bottle all the time.

I hope this helps.
