I might be overreacting but the water was crystal clear in my 2 day old 20g, but now this morning it is so cloudy. I am not worried, just wondering what this is.. did I not rinse my sand well enough? Is this new tank syndrome? I was planning on starting cycle today as I have let the tank sit for 48 hours now, the only decor is spider wood and sand, and my sponge filter from AC. Thoughts? But I can barely see the other side.
