BUT I ONLY test in the morning. I could see why it wouldn't be good to test morning one day, then night, another, because those would be different, because they are different.
BUT if I test the SAME time EVERY day, I don't see how it would really matter.
that last part is a good point.. not too sure if it would matter, as long as its the same time everyday.. maybe i should do a little bit of studying on that..
but the reason for waiting for daytime is so u dont get a low pH reading and try to do something to make it higher, cuz it will probably get higher during they day..
your most accurate pH reading will be in the middle of the light cycle, because that is when all oxygen levels will be at their best for your tank.. im sure thats why he said that at the store.
I test mine in the middle of the light cycle, every saturday. I do the water changes on sundays.
