Where to get water for testing

[Tragedyfin]

Does it make a difference where in the tank I collect the water to test it? It occured to me that since I'm taking water from the top of the tank to test I might not be getting information about lower in the tank, but I've got a filter, so theoretically the water should be all mixed? I've had a quick google, but couldn't find anything about it actually where in the tank to collect the water from. Am I being paranoid? Thanks

doesnt matter. all the water in the tank mixes together so just take it from anywhere.

It’s always easier to take from the top of the tank, but it’s all the same.

I always take water a couple of inches below the surface.

doesn't make any difference.

Temperature is (I think) the only thing of importance that will vary from the top (warmer) to the bottom (cooler). The thermometer should be closer to the top than the bottom, as the cooler lower water is natural, and it is warming the entire tank that is the important aspect and you don't want to be using the lower temperature for that. If that makes sense...
