Low pH

[Rscott]

Other then Co2
What’s a reason for low pH?

Low Alk. CO2 and Alk are the only contributors to ph in a tank. My tank runs at 7.8-8.0. Everything is happy, just grows a little slower.

My ph is 7.8-8. My Alk is 8-8.5. Wanted to clarify.

Thanks

My alk sits around 8.2
Also dosing kalkwasser
Still no improvement

As long as your ph is above 7.8, don’t stress about it. Open a window in the house in the morning when it’s cooler out to help bring down the house CO2 and that’ll help reduce CO2 in your tank. Macroalgae will also help keep ph up as it takes in CO2 from your tank.

That’s good to know because I just started a fuge today

Well it says 7.78 but who knows if the apex is calibrated right

You can run the air intake from your skimmer close to a window to get fresh air and that’ll help. Or can look into a CO2 scrubber.

Mine was 7.72 this morning and is up to 7.9 right now. I’m not overly worried. As long as your parameters are good, ph will be close.

Unreal

Just recalibrated my apex pH probe
Now says 8.3 exactly where I expect it to be.
I am really tired of this apex probe nonsense

 

[Rscott]

Just as s side note I was expecting. 8.3 because I’m dosing the kalkwasser 60ml per day
