Low PH during Hyposalinity / Help !!!

[belzebuth]

Hello All,
I am unable to keep the PH up in my QT tank during OST. I am performing daily water change but the PH never seem to creep up.

Any idea how to deal with this?

Current SG 1.009
Current PH 7.5 / this morning when the lights are off.

Thank you

get some buffer, like seachem reef buffer and add a bit of that,maybe makeshure you have enough flow in the tank for gas exchange also

Thank you I have crabs. I have purchased the Seachem buffer and added a little bit, I have also added an air stone to the tank. I will test tomorrow. The fish don't seem to stressed about it.
