My 125 gal tank has been up and running for a month. I have 90lbs of live rock, 160lbs of live sand. We also have 15 various damsel fish, two shrimp, 5 snails and three crabs. I also have a snowflake eel. The water was beautiful a few days ago but when I added more live rock the water became cloudy. I thought the water would clear up after a few days but it isn't getting any better. I think it is getting worse. It looks like there is smoke in the water. All of my levels are normal. Would a water change be beneficial or should I get something to help clear the water? Thanks!
