An issue with test kits

Recommended Posts

I saw this video the other day on Dr. Tim's and thought it was good information.

Crazy how a test kit can read a false "0" when the actual result if literally off the charts!

Reminds me of a quote from on of my daughter's cartoons -

"Captain the radiation levels are off the charts!...

....Then buy some bigger charts and take it out of petty cash!"

That's a very good video showing some of the issues with testing. Here's a link to a good article by James Fatheree and Dr. David Flanigan looking at averge aquarists testing. Towards the end they run the tests themselves and discuss why two diffent people get different results with the same test kit.
