why does NH3 go up when I do water changes?

[MISSING: System.API.no-headers]Free ammonia NH3 can go up when you do water changes because the water you use for water changes has a higher pH.
A. NH3 and NH4 always form equilibrium with pH and temperature. When we do a water change (especially if you are a lazy fish keeper) the new water will often be harder and higher pH than the water you are removing. This move to a higher pH will unlock NH4 into NH3 and the transition can happen in fractions of a second. The seneye device will report this change in pH, temperature and free ammonia
