re: Sera iron test correction
While perusing the archive I caught Dave's response to a previous letter
of mine. Something he said jogged my memory and now I have to recant
something I said. Hopefully anyone that read my original post will have an
opportunity to read this one.
I wrote in response to a letter by Bryan Bankhead:

The kit had no smell that I recalled, and that started me thinking, and I
checked some sites on the 'net. It's been more than a year since I
decided that kit was a Sera test kit, but I was wrong. The kit I had was
a Red Sea product, not a Sera product. My apologies to Dave and to the
folks at Sera. I'm back to having no opinion about the Sera kit.
The behavior that Mr. Bankhead reported (not reading much iron until the
concentrations got so high that the water was yellow as pee) was very much
what I saw from the Red Sea kit, so there's still something wrong here.

Actually, I have no need for an iron test kit, so I never replaced the Red
Sea kit that I threw out.
My question about why the heck we need 0.5 mg/l of iron in our aquariums
