So my tank has been running for about 2 days. All i have is live sand in there at the moment. I tested my water parameters (PH, Amonnia, Nitrite, and nitrate) for the first time. All of the tests except for PH, obviousl,y came back as zero. I dont really know what to take this as since im pretty new. Is this a bad thing good thing or should i just keep testing and watch it. It seems a little soon for the tank to be cycled. It is a 5g marineland contour
