So have somewhat of a quandary with my ph lately. I recently added a co2 scrubber to my skimmer to combat my consistently low ph. Before adding this my ph range was generally around 7.8-7.6, its rise and fall was fairly predictable, with it rising slightly when main lights came on and dropping when they went off and fuge light was on.
Once I added the scrubber the ph now ranges from 7.8-8.2, which is within an acceptable range, but the range is now much larger then before, which I think might have some of my corals a bit perturbed as I am not seeing quite as good of polyp extension I was before.
On top of this the rise and fall of the ph has me scratching my head. When my lights turn on around 8am the ph begins to fall and continues to through most of the day and bottoms out between the time of 5pm-midnight, generally bottoming out around 7.8. At about midnight it begins to climb back up to 8.2 until my main light come back on around 8am again.
My DT light schedule is set to adjust seasonally but generally the blues run from 8am-8pm and all the dt lights are on from 11am-4pm. The fuge lights run from 5pm-8am
The only thing I add to the tank is Kalwasser via my ato
At least for now the ph range is more in an acceptable range, and dont think this is to serious of an issue, but this shift in the rise and fall has me scratching my head a bit trying to figure why its *** backwards of what I would expect. Any one got any ideas?
