All of the seals on the lids are tight. I am just thinking that I didn't get enough O2 in there.

From what you posted originally, I think you had plenty of O2 to start with.

Just checked the gravity, it was 1.056 to start and is 1.030 7 days later. I usually don't check the gravity after one week so I am not sure if this is normal or slower than normal progress.

I started with the nutrients and O2 wand at the same time. OMG the results are awesome.

I just have to say that.

I've noticed since adding o2 that the lag time is a bit longer than I was used too. Nothing to worry about

I have been using the long agitator attachment that you put in your drill. It creates a giant vortex in the fermenter before adding the yeast starter and my beers have been bubbling the airlock in less than three hours. I usually hit it with this agitator rod 20 to30 seconds. I have used it carboys, but now prefer to use the pails for my primary and the carboys for the secondary. The pails are easier to clean and leave a few inches for krausen and foam, so no losses like when i was using the blowoff system in a carboy.

I believe that is normal. The yeast will use oxygen to build their cell walls and replicate while the oxygen lasts. Once the oxygen is scarce, they will start fermentation. Even with the added lag time, fermentation should generally be quicker with the O2 as there should be more healthy yeast to do the job.

Yesterday I had a small leak in the connection of the wand and the O2 bottle so I did not have much in the tank toadd to the boilled wort. So I aerated this by using a drill and a dedicated paint mixer. Now i have a fresh bottle of O2 and want to know if 24 hours later is too late to bother adding O2 at this point?

If the yeast have already started active fermentation, don't add more O2.

The airlocks are bubbling so I will not be adding any O2 at this point. Thanks for letting me know.
