PH High

[gleach]

Can anyone give me an idea of why my PH might be high? And api test kits accurate enough to determine a level of 8.30?

Without checking my API kit I would think it could read 8.3???
What pH are you shooting for?
I try to keep mine at 8.2...
Do you think 8.3 is high??
I would not worry over 8.3 myself..

It's at between 8.3 8.4 solid. But I was 8.3 8.2 I'm trying to determine why it fluctuated. I'm thinking my probe may be bad I recalibrate it but I'm not sure?

I would not worry about it. 8.0 to 8.4 is fine IMO.

The time of day depending on your lighting cycle ,

Surface agitation

Aeration in the room like in the winter you have windows closed so higher levels of Carbon Dioxide present.

Also Alk


Can all play a part in your PH some fluctuations are normal throughout a 24 hour cycle

Try and test it at the same time each day you will find it will normally be the same.

Yeah all I can think is I'm might me dosing much alk or my probe is off.

Also test your PH about an hour before the lights go out.
