Sorry I missed this thread. I have been out of the hobby for a while now due to a happy but too busy life with four young kids. I do hope you all get this topic worked out by the time the kids are all in college and I can restart the tanks.
I wanted to add a link to this old thread that has a plethora of information for anyone still looking into this
