A little background that led me to this post... I was testing my chlorine yesterday with FAS/DPD method. I usually take the pool sample in a small bottle to carry into the house because I find it easier to measure sitting down at a table. Anyhow, I got distracted multi-tasking and the sample was probably sitting around for at least 30 minutes. The resulting test came back 6.0 and I was immediately suspicious because it had been much higher the night before. (I'm currently adjusting my SWG output.) Took a fresh sample from the pool and immediately re-ran the test and sure enough it was 11.0. The obvious moral of the story is you can't leave your test sample sitting around too long as chlorine "dissipates" and/or is affected by chloramines, etc.
But that got me to thinking that I didn't recall seeing that advice/warning specifically stated anywhere. So I decided to look around the TFP Pool School pages and found it really wasn't covered.
As usual, I then dove into the Wiki and found a reference in the "Testing Process" section of "Water Testing Errors - Further Reading". To be honest, that isn't where I expected to find it because I naturally first reviewed the "Water Testing Instructions - Further Reading" page.
So I recommend adding a new page titled something like "How to Test Your Water Chemistry" to the Pool School/Pool Care Basics page. It should include some or all of the tips from the "Testing Process" section of the "Water Testing Errors" page. I'd expect this would be especially helpful for those infamous "newbies" that don't know as much about testing. (Or us old folks that sometimes get distracted or forget.
)
