The bucket has a lid on it and the tubing going into it is very tight, but I do have a small pressure relief hole in the lid..Should I be worried?

Sniff it. Ozone has a particular smell to it, and once you know that smell you can easily recognize it. I'm not sure I could smell ozone over some stinky skimmate though. Use a new bucket in place of the skimmate bucket for 10 mins, then sniff the bucket.
