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

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. Graham.

I think you are correct. The water sample used in the Nutrafin test must have been contaminated. I have tested the water several times since my post and both kits are in general agreement, my old eyes can't discern the subtle color changes in the Nutrafin kit that well. Both kits seem to give results suitable for my use. Al "Graham Broadbridge" wrote in message . .. "Tasslehoff" wrote in message . .. The Red Sea test.
