I assume your dosing manually. Split your dosing up as the .5 dkh swing is not good. Even if you just do half in the am and half in the pm that spike is not good. It’s best to do it over 24 hours to try to keep it stable tho. 7.9 ph is fine.

The cyclical trend is nothing to worry about, that 8.6 jump looks a little strange but it may be a blip. The natural trend for the pH in the tank is to go down at night and increase during the day. It has to do with the respiration cycle of the algae and its consumption of oxygen and CO2 throughout the day.
Your pH trends looks similar to mine. The little 0.2 bumps in pH at the 12am and 6am are from alk doses. It even shows the low pH at the beginning from the family being in the house more around the July 4th holiday. There was an elevated level of CO2 in the house in around that time. The blue is the light cycle in my tank. You can see the pH responding as the lights go up and down causing the algae to photosynthesis which effects pH.

Great advice, thanks
I’ve been dosing last thing at night, because I thought that it would keep
On top of the drop in PH overnight. Should I split the doses into morning and evening?

Why are you having your pH get so high? I’ve never personally seen success with that high of pH. Most shoot between 8-8.3
That being said, you want stability. Swings stress out corals. I would cut your dosing into smaller amounts over the course of the day. Are you manually dosing or using a dosing pump?

I’m manually dosing, but looking into a automatic doser at the moment. Undecided which though.
It peaks I guess when I dose?
I see an automatic spike up to 8.6
I’ll split the doses into 2 in the day?
I dose 1.5ml to keep my KH around about 7.4
1.5ml per day is my maintenance dose.
Thanks

So the spikes are from when you are manually dosing, correct? What’s your typical pH if you weren’t dosing?

My PH has been dropping to about 7.99 at 8am in the morning. I dose at about 9pm at night just before lights out. Usually my PH stays just above 8 until the lights go on at 9am but recently been going below 8.

It’s normal & nothing to worry about. For certain, it’s not an EMERGENCY. Healthy reefs of the ocean fluctuate as much as .5 pH units.
