Is my LFS owner yanking my chain?

Well, its been 7 days and since I've set up the tank. I've done daily water tests and decided to keep them in a spreadsheet. Here is the tank progress "graphically". I think it would be kinda cool to be able to graph a few months/years worth of data.

 

i think you'll find it getting very old,. very fast.

PS i find licking suction caps makes them good, not always the best taste. But if it helps em stick...
