pH swings

[Vincent100]

Hi all
Below is a screenshot from my apex
Should I be worried about my pH swings
My lfs reckon it's because I don't dose through the night , not sure if that's it or not so any info on this would be great
Tank is thriving so not to worried but would like to get it more stable if possible
I'v no fresh air line running to my tank and my house is pretty well sealed
Sump light comes on when dt lights go off and goes off when they come on ......
Thanks

What are your water pramameters? What are you dosing?

The lows are pretty low, if accurate. The swing itself is not an issue.

Triton core 7,
Alk 8.0 dKH
Cal 450 ppm , had to let it drop over the last 2 weeks as pump was dripping into the sump and made my Cal rise high but is now back stable at 450 ppm

Mag not sure anymore as i'v gave up testing but will be stable because the Triton doseing method

Aside of installing a CO2 scrubber or running a outside airline to your skimmer, adding Kalkwasser could help with the PH swings. Im not sure how that would effect your Triton core dosing, since I'm not familiar with that system.
