Closet Doms in Water.... An Ad Hoc Log of Black Dominas in DWC Hydro

[MVP]

I've heard from many sources that Hanna's suck, unless you buy their most expensive model or two.

Well add me to that list regarding their pHep4 pen. I was so pissed off I ordered a $25 Milwaukee to see if the Hanna was correct or not. The Cheapie pen reads exactly what the old school PH test kit does. The Hanna reads 0.8 - 1.1 higher than the kit! Piece O Crap!!!
