Yeah, I thought mine was too.
My kit has been reading 0.08 for over a year. I chalked it up to me being awesome and having a really stable tank. Boy was I wrong.
I finally pulled the trigger on a Hanna Phosphate colorimeter. It arrived last night, so naturally I used it. I like to play with my new toys immediately. Well it read 0.2!
If you are using Red Sea phosphate kits, beware of this problem. Especially since I have seen multiple threads where someone says their PO4 is 0.08 using the Red Sea kit.
