Is there a zero phosphate reading? I just bought this checker and tested my aquarium. its read zero. Just curious.

Yes....its accuracy is only +/- .04ppm so even with a .00 reading your phosphate could be any where from .000000 to .04ppm.

Some thing also to check, is that they have a Hanna checker out, that reads PPB, It's an ULR phosphate reader. I have a reading of .0004ppb in my tank.

I can't remember the details exactly but I remember reading a thread were Randy Holmes Farley explains that the ULR phosphorus checker is not much more accurate than the phosphate checker.
