First - do not raise the pH quickly - it can be deadly to your fish!

Are you properly aerating your water change water before using it?
Is the room your tank is in exposed daily to fresh air through an open window?
Do you have a light over your fuge/sump that runs on the opposite schedule as the lights on your DT?

All of these things will help (gently) raise the pH of your water. In combination with water changes you should be able to get the pH back to the 8.1 range in a week or so.

Also remember that pH readings will be higher during the day than at night. What time of day did you measure the pH and did you run the test more than once so you are sure it is a correct reading? If using a probe - have you calibrated it recently?

24hrs aerating the watet b4 WC, tank has an open air, no cover, fuge light is alternating with DT, im using red see test kit.

Oh, i took the test last night at 8pm and repeated the test this afternoon, around 6pm. Same reading.

What are you other parameters - especially your Alk?

Mag- 1520
CA- 410
Alk-9.0
NO3- .75
PHO- .20

And the pH stays at 7.8 for the whole day? A daily swings of pH are quite normal, you should have a pH of 8.2, but mine drops to 7.9 during the night cycle and comes back to 8.2 during the photoperiod.

I'll test it again tomorrow, I'm dozing kalk on my auto top off and dual reactor GFO.
