Wow 500 gallons per minute!! That's awesome!! Sorry I didn't think it was that much! You could make a serious fountain out of that. With that much GPM you could have a nice spout of water. Only thing is them you would lose your circulation that you are getting. I like circulation I think that help too. Some folks would argue that circulation is better than areation.... Not to sure about that though???
