Just a quick question and hopefully a quick answer.
I have just purchased a Ph Pen (cheapy from Amazon), I have bought some de-ionised water to calibrate with, then I read on the solution packs that ph changes with temperature, for me to calibrate correctly do I need to make sure the solution is at 25c?
 
There is a correction factor.. :) @ 25°C this factor is 0

Here are the factors in our average ranges.

As you can see it is into 0.10 at the most.. Fairly neglectable, but if you want to go nerdy.. See this.

So I don't need to worry about water temp when mixing.

Look at it like this.. :) In the red square is our average temp range for indoor aqaurium.. Red cross is no go for us. But still see how little the blabla differences are.. Neglectable... :)
