I've found on the 22nd December, 2009 PE wrote the following on APUG in the thread "D-76, pH elevation with storage":
When I have mixed D76, I bottle it in air tight containers and use when it has cooled, which may be several days or weeks later. Are you suggesting that when I mix it in a bucket I should leave this for 24 hours before storage to allow contact with air for this oxygen thingy?
