Doing an ati water test

[steallife904]

Going to do a ATI water test for the first time. Should I do a water change before I take the water samples? Was going to do a water change tonight, then collect water to send off. Does it matter?

Take the sample before the water change. It's not a grade on your reefing skills. It's a diagnostic tool. You want to know what it look like at its worst.

about how long has it taken you to get result back and how will I know when I do? I sent mine out 11/23/19, still nothing back. I did get a message when I created my account that they no longer email you to let you know they received test or let you know when complete. Do I just have to keep logging on and checking? And when I do what will I see? A new analyst for my tank?
