Salifert PH test confusion

Hi,

Yesterday I noticed that my PH tested 8.0 on the salifert color
test. I added Kent superbuffer that I sometimes do between water
changes every (two weeks), when the alk. and PH get out of wack.
Yesterday I went to check the PH and the color was RED?! I got
neverous and added another treatment of the Kent supper buffer, and I
plan to test the PH again tonight when I get home. The few soft
corals, open brain I have and fish seem ok. Does anybody know if red
is too high or too low, I can't tell because its off the scale.

Anyway tank parms a

ALK ~300 Hardness ~9 (this is from memory, tested last night) If red
is low PH
I thought that the alk. would also be low.

Nitrates = No reading effectively zero ( The tank is mature and has a
low bioload so I didn't test nitrites or ammonia).

I changed salt mixes from IO to reef crystals (I plan on adding more
corals before adding any more fish - curently flame hawk, and false
percula clown).

My PH always drops from a water change where it is in the 8.0-8.3
range consistently until the next WC, but never this far(I am assuming
that RED means low)

Does anybody have any idea whats up and/or suggestions to keep things
in balance? I forgot to mention this is a 30g tank with LS and 60 lbs
of live rock.

TIA,

Bill
