The Red Sea test. The Hagen one is supposed to be bogus in Australia.

Hi
I am trying to measure the Phosphate levels in my tank. Using a Red Sea
test
kit the level is about .1 while a Nutrafin (Hagen) measures about 5.
Both
kits are about one month old. Which one should I believe?

Something is either wrong with the Hagen test kit, or perhaps it's been
contaminated with phosphate.

I'm not sure why anyone would think the Hagen test kit has problems specific
to Australia. I'm in Australia (Sydney) and I've had the Hagen kit tested
by a Pharmacist friend of mine in their lab, and the Hagen test kit is
accurate enough for hobby use.
