phosphate testing

[Johnny Reefer]

Ya, after reading some responses, I'm tending to agree that this PO4 testing is overrated, too, and that the tank itself is the best parameter. I guess my curiousity gets the better of me. That, and I shelled out 250 bucks for this thing and now that I have it I'd like to know how to work the damn thing. In hindsight, a waste of $, I suppose. I'll see if I can find any talk of the Hanna on RC.

Thanx much,
