Water reading

[Emelinda76]

When is it best to test your water to have a more accurate reading? Morning , mid or late day, or evening? Does it really make a difference?

You need to pick a time and stick with it for consistency. pH is the only item that is truly affected and that is by how long the lights have been on. pH will be lowest just before lights on and highest just before lights off.

I'm about to do my tests now (Sunday monring).
