Who tests their water-change mix?

Ah, makes sense. But if you have larger changes to make, I'd certainly do it in the mixing vessel first. My salt required me to adjust the Ca (separate additive), so it has to be done out of the tank first.

I just realized I haven't tested pH in a VERY long time... I think my testing schedule needs an overhaul.
