Hi all,
My Ph is consistently below 7.90 during all day and below 7.7 at night according to APEX probe (recently calibrated), while Alkalinity is 12.6
And I can't understand why this is happening.
I already have a CO2 scrubber running into the Skimmer air line.
Already tried opening windows which did not have any effect.
I make 20% water changes every 2 weeks.
Using Redsea Coral Pro salt.
Don't want to use a buffer as my Kh is already very high.
Any suggestions, please?
It's an LPS tank with anemones.
Salinity 34.4
Calcium 450
Nitrate 2
Phosphates 0.02
Ammonia 0
Also running Carbon and GFO in reactor
Thanks in advance
