pH Fluctuation and Levels

[Michael Hull]

New to APEX and both loving it and being overwhelmed by data and tracking. Are these levels and fluctuations OK?

That most recent drop in last day is cus I threw in a dose of Melafix to help with some fin nipping on our Marine Betta, but I think its holding just fine. I'm going to start with kalk in Tunze ATO once I get through this period, and am testing Alk twice daily right now.

Those readings look normal to me based on lights being on or off.

I am relatively new to the Apex also. My tank has a similar pattern of pH rising and falling over 24 hours. It is normal and expected. Watching the various parameters rise and fall is like watching the tank ecosystem breathe over the course of time. Very different then discrete testing.

If you look at an actual comparison of the pH rise and fall with the main display lights, you see a bit of a time offset. In this case, tan/orange is the pH, pink the T5 lights (amps), and purple the LED lights (amps).

It turns out that tank temperature and pH are more closely aligned temporally. Orange is pH and green is temperature.
