I have just been testing my tank for nitrate and I am now not sure which test I should trust. I have used a red sea and a salifert kit, the red sea kit said I have Nitrate of 36 ppm and the salifert said 2.5 ppm. Everything else in the tank is testing fine just the nitrate test that is the...

Iv seen online that the NT Aquarium Lab kit is a whole lot cheaper than the marine version and includes more testing liquids. Are these just the same tests but differently priced to make more money from mariners? Or am I just better off getting the marine versions? Currently been using API and...
