If it it really is a water profile issue, it probably won't fade. Ask your municipal water works for a mineral analysis or send a sample off to Ward labs.
mpenn35, Thanks you for the compliments. I am the manager at GF and it's good to hear that we're hitting the mark. Please let me know when you're in next and introduce yourself!

It's all about surface area. You've got a ton of surface submerged in the beer with an immersion chiller, and copper is REALLY effective at transferring heat.
There's absolutely no reason that an average gravity beer should take more than 7 days to reach FG. Now, if we're talking clarity or flavor development, that's another story. Bottling in seven days should not result in bombs if you pitch the proper amount of yeast and oxygenate your wort.
IF I were in the market for a reader, I would consider the iPad. Just keep in mind, Apple didn't design it to be marketable to everyone. With that in mind, I believe that it will still affect the landscape of mobile computing.
