I'm currently using API master test kit for freshwater, and all of my tanks are testing 0 for ammonia, nitrite, and nitrate. I'm confused because in almost all cases you will have some readings of nitrate. is this correct? does the term of the tank being established have anything to do with levels of nitrate? My tanks in gallons are 55, 29, and 2 10's. soon i will be setting up a 65 discus tank, and i know how their wanter needs to be, and if this test kit is not accurate, i wont be able to keep my water perfect. any info on this topic would be much appreciated. thanks
