Hi,

I made a quick search and found out that most hobbyist NH3 test kits are not very sensitive. The best I could find are the LaMotte 7418-02 (0,03 ppm NH3) and 3304 (0,06 ppm NH3) kits. The 3304 is designed to be used in saltwater only, the 7418-02 is for both fresh- and saltwater.

1) Does anyone know better test kits to be used in a reef tank?
2) I remember that some ammonium test methods have interferences from calcium and some other ions found in seawater. Is this a issue with common test kits or is the sample prepared somehow before testing by kits using these methods?

TIA!
