I know that I deserve a beating for this, but I have been using my test kit for several months now and today was the first time I tried running the reference test sample. It was supposed to show 1ppm, but came up ZERO. I shook the bottle, ran it several times over, and 0ppm was always the result. :censor:
Soooooo after several months of battling green water/hair algae, dosing and testing constantly to maintain a 10:1 ratio, purchasing a UV
sterilizer, replanting twice in frustration, and nearly losing all hope....it is possible that my test kit is a dud?
I don't have access to another kit, so either my test is bad or the reference sample is bad and I have no way of figuring which? No LFS
does water testing here in town either. Any advice?
