Just started up a saltwater tank 4 days ago. I put my rock in and then my sand and water. It has been 4 days and my water is still somewhat cloudy. I'm just trying to figure out if this is normal or if I did something wrong. It's a 90 gallon tank with 2 penguin 350s. I used the clarifier that came with the sand. Circulation pump is off. Sand is oolite. I have been rinsing my filters quite a bit to keep particles from clogging them. Could it be that I didn't clean my rock well enough? Or am I just freaking out?
