So, I'm finally all set up and running. Currently cycling the live rock directly in the tank. I bought some nice pieces... If you look at the close up shot, you'll see that the middle rock is actually a den!! I found just the right piece ~ its actually bowl shaped, very spacious, and provides another exit out the back, I think it's perfect for an octopus!! Now... my dust problem (see pics below). I rinsed the sand very well, so I know it's not sand dust... also because there was bits floating around before I even added anything. I thought the water would have settled or filtered by now. I'm thinking that it might be either dust from having the tank sitting on the LFS shelf or acrylic dust when I had drilled my external overflow. I thought I had done a pretty nice job of rinsing out the tank, but its hard in a onebedroom apartment. Any advice on how to fix this? I tried siphoning some water through a sock filter and returned the water... The tank has only been running for two days now. The exposure makes the bits look like worms... but they are really fine particles. Smaller than microbubbles even and swirl in every direction in the tank.
