Placed live rock in a day ago, measurements are all 0??
Hey guys, this is my first saltwater tank so I apologize if I am just totally missing something here.
I had my tank set up and let the water circulate for a few days. I put in my liverock yesterday. Half of it was from an established tank that was torn down and had been sitting in a bucket of saltwater for a week. The other half was purchased offline, came damp and looked like there was some decent life on it.
So my question is, I know that to tell when the tank has cycled you should have 0 readings on nitrite, ammonia, and a reading on the nitrate, but I tested the water right after putting my rock in yesterday and again today and the nitrite and ammonia was 0 and there was a reading on the nitrate. I know my tank could not possibly have cycled yet, so my my question is what is the reason for the 0 readings?
