I use the Tetra Nitrate testing kit. It has read 0 since I got it. The
next readable measurement in the kit is 12.5. I was wondering what a better
kit would be. Has anyone dealt with Hach? Which particular one is the best
for us? Also, my tank has been reading 0 phosphates ever since I started
testing with the Dupla kit. Does anyone know how to supplement the tank for
phosphates? What dose?
