Hi there,
I just received package with my checker from Oceanic and i did some tests, how can I tell if the checker is actually working properly? I tested water from my tank and reeds - 0.00 (I don't think so, based on problems what I have right now) New mixed water - 0.00 too, water from tap - 0.00. I followed instruction included with checker, i did what OC-Eugen suggested, some results, what i'm doing wrong???
Thanks
