I have had my tank set up for 1 month and the water is still cloudy. Lights have been off, and all that currently is in the tank is live sand. I know that cloudy water is normal on new tanks, but didn’t think it would still be 1 month later. My LFS recommended me to get a UV sterilizer at $400, but others say don’t buy; as the water will eventually clear up on its own. Thoughts?
