dKH at night time

[Lenny]

Hi guys,

So the guy at the LFS told me that at night the dKH will be different from day time.

I did a test at my dKH at night is at 8.

Day time is at 9-10. Is that in the normal range?

PH tends to fluctuate, higher in the day & lower at night, fluctuation mitigated by running reverse light cycle in refugium or consistently higher KH to buffer..

As for KH, Your KH movement is rather high, about 2 pts a day? Possible if you are keeping lots of SPS & clams?

What's your dosing regime like? Add KH in the morning at one go & allow corals to consume thruout the day?

Just to add on... 8-10 is within the acceptable range of 7-11, so you are ok. 

I'm curious however, with the fluctuations that you are seeing daily.. If you have SPS best to have it as stable as possible

HI JMW,

Thank you so much for your explanation.
No i'm not dosing anything at all. And no SPS. Just simple LPS which are still small.
I'll keep monitoring it.
