I recently added some more live sand to my 58g tank and some live rock in the sump and POOF, my tank is cloudy. I tried doing a 15 gallon water change and adding some carbon but no luck. My skimmer also stopped skimming, don't know why??? I have taken the live rock out of the sump but the water is still cloudy. What else can I try??? It's been cloudy for about a day or so?? HELP!!
