Molybdenum is known to be generally elevated, but is not know to be a concern, IMO.
I find them to more accurate than my home hobby test kits.
How do you know they are accurate?

Again I'm using simple hobby test kits. Like for example my NO3/PO4 reads 0 on my test kits. Well i know I have some in the water and AWT found my PO4 @.220 and NO3 @ .4. Now I'm not saying they are 100% right but i do feel they give more accurate results than my test kits.
