Ph

[bunzaroo]

I am having a hard time w/ my PH. All my other paramater are good, Calcium is always between 480 - 520, My Ph is always at 7.8. I use kent sea salt. The corals and fish are doing great. Should I worry? The tank is appx 4.5 months old, thanks

have you tried adding buffer when you do your water changes?

Mine was farely low and adding buffer helped raise it back up to 8.3

7.8 is nothing to worry about. If it's dropping below that then I would suspect poor gas exchange. Check out these links:

It could be high CO2 in your house too.

mine is 7.8 pretty consistently because i sit for so long watching my tank breathing on it, but i only have 10g to worry about
opening a window and getting airflow through the room has raised mine to 7.9 or 8.0 a couple times
