			 Hey guys, out of my own curiosity... Does PH shift frequently?  I had always thought that since I don't use supplements that I did not have to worry as much.  I think that the last time I checked ph was at least 4 months ago.  Come to think of it though, a lot has changed in the tank since then i.e. New lights, Summer temps, etc.
