ICP Water Analysis

[Tonii]

Good evening guys,

So I bought an ICP water analysis test but I have a question as to when to collect the water sample. Would it be better to collect the water sample just before or after a water change?

I chose to do mine before. I want to know what the levels are before I dilute them.

That's what I was thinking but I wasn't sure. Thanks

I just packed up my first one to send out.
