Hello People....

My PH has dropped from normally about 8.0 during the day
to 7.8 during the day and down to 7.6 at night....

I even have a tiny refugium in the back of this 25 gallon reef...of which the light is on at night only...

My ALK is at 10...

Question,....a) should I use a pH buffer? If so what one do you recommend?
b) if I boost the Ph will it raise the ALK also as I dont want that
???
Pls advise
thx,
Tim C) any idea why ph has dropped? Would adding Phyto drop it? Thx.
