Hi all,
I am wondering why my pH is so low. I am hitting 7.7 at night and 7.8 at end of the day. I am starting to get worried as occasionally I dip below 7.7 some nights.
70 gal display, 40 gallon sump
Parameters
Alkalinity: 9.7 verified 2 ways
Calcium: 458 verified 1 way
Nitrate: <5 ppm
Phosphate: zeros on ppm Hanna
Misc: vodka dosing 5 ml a day, occasional prodibio biodigest addition
Brs 2 part with soda ash (about 20 ml of both a day)
Over-sized skimmer
Probably heavy bio load /a few tangs
Steps I have taken: added very large air stone disk (5 inches opened windows all day) managed to hit 7.85 but is dropping now that lights are off.
Does a fuge make that big of a difference?
