I'm mostly sps and growing. Is a phosphorous test kit worth getting? Or will my "liquid phosphate guess the colour and be within 0.5ppm depending on light test kit" be enough? I'm all about accuracy but are ppBillion (sounds tiny) going to have a major impact?
I run gfo and change it out pretty religiously seemingly even if it doesn't need it. I'm having good although slow growth. I hope to get magnesium and a few other testers soon so I'm interested in others experiences.
