Marc & quiksilver: Thank you both very much.
ClownReef®: That was my initial thought also when I was originally asked.
But I would agree that, at least for me, it's always interesting to see how featured tanks are doing after time has elapsed.
orangekush4: Thanks Kevin for the kind words.
jdfenn81: The tank is 2'x2'x8' in dimension.
tfp: Thanks Tim. I appreciate that.
In regards to the air injection system, I made up a graphic to illustrate how it's done in my tank. Unfortunately, this didn't make it into the article so here it is for those interested...
