Ok this is driving me nuts. My water is not cloudy but it has these floaty things in it. Like sand particles. I don't have much in my tank and it's completely cycled. About 2 months old. It has a urchin, some snails, one strawberry crab that I never see, one coral banded shrimp that I never see, one serpent sea star, 4 reef hermit crabs, 2 perc clown fish and 1 lawnmower blenny. The tank is 24 gal
nano cube. Oh and I have sand sifting star fish that doesn't really bury in the sand crusises the top of the sand all night. He is quite small. Is he the problem? I looks like sand floating all over the place. I am tempted to put some sort of cloth over the water spout to "sift" out the particles but I'm scared I'll sift out the salt as well. What do I do about this?
