slowing down PH rise

[SeeFu]

Is there a way to slow down how fast the PH rises when my lights are on?

Need more details on your tank and the pH levels you are concerned about.

Certainly, but why would you want to?

This is my ph chart.

at night i dose Kwalkwasser and in the day i dose soda ash. from 12am-6am i also use a co2 scrubber. i do these additions at night to slow down the rate of ph decrease. i also have my skimmer set to turn off at ph of 8.45 and lights turn off at ph of 8.5. i'd like to find a way to slow my ph rise so that my skimmer and lights dont turn off before they're supposed to turn off. lights are on a 10 hr cycle w/ a 1 hr ramp up and down.. lights turn on at 12pm and off at 10pm

I do something similar to you except I turn off the skimmer which has a c02 scrubber at 8.31 and turn it on at 8.28. This allows the my pH to swing between 8.28 and 8.42 daily. No need for me to ever cut my lighting schedule short.

i have my c02 scrubber set to on from 12am-6am and then it stays off until ph drops under 8.15

even w/ my skimmer off, my ph will continue to rise quickly.

Why do you want to turn off your skimmer at pH 8.45 and turn off lights at pH 8.5?

There's nothing wrong with pH going up to pH 8.55.

I experienced pH as high as 8.65 and no problems at all corals loved the high pH.
