tedr108 > thanks for your response. I'm going to try to drill a hole and like you said install a valve to release the air. Hopefully it will fill up.

I do remember the Tom's DIY reactor. I had wanted to make it but I figured there's no point to scrap the old one since it's been working until now.

I will keep my existing reactor for the time being and make Tom's as my next reactor.

Thanks for your help ted!
