PH Readings from Seneye. Your thoughts?

So I recently got the SENEYE Reef Aquarium Monitor and Par Meter and was able to take some PH readings. I just recently installed co2 and even though I was taking manual PH/KH tests it was becoming very tedious. So just had to put the sensor into the tank and was able to get readings all the way from 6pm last night to tonight. Here are what my readings are. I wanted to ask if this looks ok for pressurized co2. I am still trying to dial in my co2 so want to get your thoughts. co2 turns on at 6:30am and lights are on at 7:00am. co2 turns off at 4:30pm and lights are off at 5:30pm.

6pm=7.35
7am=8.03
8am=7.72
9am=7.59
10am=7.49
11am=7.46
12pm=7.39
1pm=7.26
2pm=7.22
3pm=7.26
4pm=7.33
5pm=7.34
6pm=7.35

For a pressurized system these results don't look so good.
A drop of 1.0 in pH = 30ppm of CO2.

Is that first reading supposed to be 6am? It's a little confusing. Ideally you would want to look at the readings right before the Co2 comes on. And then, as Maryland said, try to target a full 1 point drop in PH by the time the lights come on. It may dip a little farther than 1 point (1.1 - 1.3) after that until the plants really get using it. And you may have to start your co2 earlier to get to that point. I would suggest waiting to turn up co2 until you can be around for the whole day so you can keep an eye on your fish. You don't want to turn it up too much and gas them while you're not around.

Oh ok. So after the plants start using it, it should typically stop dropping correct? Should it typically stay at the lowest point during the day while the plants are using the co2, so the same point right before the plants start using the co2? Sorry I am very new to co2. This is why I posted this to get it all cleared up for me. Thank you for your help.

Bump: I left my laptop on all night monitoring the ph. So the co2 came on at 5:30 and the lights came on at 7:00am.

5:20am(right before co2 came on)
7.73 PH
7:00am(right when lights came on)
7.39 PH

I am here today and will be monitoring the co2 all day. Adjusted up a bit higher the bps and will continue to watch PH and the drop checker. Will do same test tomorrow morning and hopefully will be at least a .75 ph difference from start of co2 to lights. Thanks Maryland and elusive77 for your input. Why I love this site so much.

Yeah, it definitely needs to be higher. Turn it up slowly until you get that 1 point drop before lights on. I'm not sure if the PH continues to drop or if it levels out at some point in my tank. I haven't really watched it that closely, since I just have a PH pen. It probably depends on your co2 rate. If you're putting in more than the plants are using, then it should climb slowly throughout the day. This is not an issue unless it gets too high later in the day and your fish are gasping. If that happens, just decrease the co2 rate a little and start your co2 a little earlier to compensate. With your Seneye you should be able to dial it in nicely though. I'm jealous of that.

What if it continues to drop throughout the day? Because at the lights on it was at at 7.39 but now it is at 7.10. All the fish seem fine acting normal and the drop checker is at a good green.

So I have a laptop which is continually monitoring my PH while I dial in my co2. So I noticed something weird. It was going down slowly from 5:30am (time the co2 came on) then it spiked up roughly 6 hours later from 6.80 ph to 7.10 ph within 30 minutes. Is this normal? Why the sudden spike? Sorry everyone again I am really new to co2. I did not adjust my co2 at that time I only adjusted it first thing this morning at about 7:30am. Again in the graph the time right before the spike was actually 11:40 am then spiked that high up at 12:00pm so 20 minutes it went from 6.8ph to 7.10ph.

Bump:
