Best time to test params?

[Jarred Darque]

Is ther a best time, i.e. time after lights have been turned on/off that is best to test for acurate parameters?

If there is I dont know about it. I just check it out when I can.

The best time to test your parameters is the same time every day

What exact time that is shouldn't matter a great deal but you should consider your system's setup. If you don't have a sump with a counter light schedule then your Ph will fluctuate with your light schedule due to the change in O2 levels. If you have a sump that is lit when your main is unlit then your Ph and O2 levels should stay more consistant. Other than that there shouldn't be a great deal of change in water parameteres throughout the day.

I agree with the rest, unless testing for pH. You should try to test before lights out and then again in the morning around lights on, but at the same time.
