I was just wondering if using a 5 gallon diluted batch of idophore for two days in a row is acceptable. Ill be racking to a secondary Friday night, then having a brew day with my buddies on Saturday. Thanks!
Generally it's effectiveness dissipates within 24 hours if left open. I think you will find it on the bottle, that it is still effective if it is still brown. You might want to add another capful for the second day.
