In my DWC setup I have a drain spout, so with this I take a 100ml test vile fill it twice dump back in and On the third fill I use that for testing PH EC and PPM, now when I open the lid and test from the top of the res I get different PH PPM and EC not big differences maybe a .1 or .2 on PH maybe 100 or so on PPM. So I’m curious which would be the better point to test for better precision?
@Aqua Man alright so how about this not really sure if it would do anything but for tap water if I got spare bucket and air pump to put air through for a few days before using it for nute mix, will that help dissolve some of the PPM content like chlormine and stuff

Probably not.. most water supplies use chloramine and the ppm won't drop... chlorine/chloramine has a max in tap water of 4 ppm and usually only around 1ppm. Chloramine cannot be aerated out you need to use ascorbic acid or something to break the bond with the ammonia and chlorine. Then it can be aerated out. If your water supply using chlorine only then yes you can aerate it out
