Ph

my tank was sitting at 8.4 on the ph and now it is 8.2???? is there something i should do about this? if so what is it ?

8.2 is a good number. Don't mess with it. Small fluctuations are not uncommon. Large rapid swings are cause for worry.

How did it change? Do you run lights at night? At night the pH will naturally go down because photosynthesis stops. When the lights come back on the pH will rise throughout the day since photosynthesis is continued. At what times did you check the pH to get the difference? It should be ok as long as the pH doesn't change more then .2 in a 24 hour period. The key is that the pH is kept as stable as possible.
