I've had my O for roughly a month (after i fully cycled the tank ) everyone talks about water changes, i know they are important! Yet i just tested the water today with the master kit- everything was perfect!

i do loose a lot of h20 from evaporation, so i've been adding maybe 1/4 gal a day of fresh water... Still havent done a major wc, and everything still jives. Am i missing something or do some people over exaggerate the frequency of their wcs? (Ps im on clean well water- no chlorine or city chems)....
