Hi, is it normal for nitrates to be at 0 in a 23l fluval edge? I feed 4 tetra glowlights 1 flake each per day do a 25% pwc a week. Amm at 0 and nitrites at 0 usng api liquid master test...

Yeah, it's bottle #2 for 30 seconds, and the entire test tube for a solid minute. It'll completely throw the results if you don't. Is the tank heavily planted?

Also, how long has it been running?

Same thing happened to me. I retested and my nitrates were 40
