I just set up a new 10 gallon nano tank with the plan to make it s reef tank. 2 weeks ago, I added live sand, all 10 gallons which came from an already well established tank, a small hanging refugium and chaeto algae with copepods. Throughout the past 2 weeks, I've been chemistry testing and there were no signs that the maturation process has started. So far, there have been no levels of ammonia, nitrite, or nitrate. There are bubbles forming on top of the sand bed which I assume is micro algae and bacteria creating gasses. Does anybody have any idea why there is no ammonia, nitrite or nitrate in my tank?
