Raising PH
 

After adding a WEIPRO PH controller to my reef I noticed that maximum is about 8.1 but later afternoon it drops to around 7.8 even sometimes 7.6.

The display tank is on for 12 hours, 1 hour before they switch off turn on the refugium lights that run for around 20 hours. I also dose kalk everyday 24/7.

What should I do to raise the PH?

Kalk will raise your pH... 7.5-8.5 is completely acceptable though.

Just to add,

make sure your alkalinity(KA) is in the proper range of 9-11 dkh.

By raising your ph with kalk you can lead to big PH swings if not buffered.

Do you use an AC adaptor? Mine does this on the AC adaptor not as low but low enough.

I have a CO2 bottle connected with the WEIPRO Controller, it is set that when the PH goes higher then 8.3, open the solenoid valve and it dose CO2 to reduce the high PH reading.

But my problem is that I wish to keep it stable around 8.0 - 8.2.
