Need Help with Brings PH to 8.0

[ANIMALHOUSE]

yeah, i'm trying to stay away from chemicals.

If i'm trying to go from 6.8 to 7.8 is this bringing the PH up or Down.

Kind of confused now.

If you're going from 6.8 to 7.5 that's going up... For me i got a few big chunks of coral from my lfs and dropped it in my FX5 to raise my ph.. Mine went from 6.0 to 7.0 with in a day.. And liek others have said if you add wood it will LOWER/DROP your ph...
