Yea i need a new Nitrate test, but im not sure i want to be a backyard chemist. I have the ALK and the PHOS, and run salifert for MAG. I need to source something new for nitrates. For new tanks i just use remaining API to at least make sure im getting readings, but long term i need a better solution.Im going to wait a bit and see what people think first. I use the Nyos for no3 currently and its really simple and easy to read...
