can some one explain to me on nocturnal change for the ph probe?

[chercm]

i read the manual but do not quite understand

what does it mean by the change of some ph and the start and end time ?

does it mean i can switch the ph probe off at that time ?

It means you can program for a different pH tank value at nights, important for planted tanks especially.

i am using the ph probe to be used on the CR , how to program that it will switch off the ph probe or co2 at night ?

What about to program a higher nominal value at night with the help of the nocturnal change?

What about to program a higher nominal value at night with the help of the nocturnal change?

Choose a value that is higher than 6,7 and test if this helps.
