Hey all hope your all enjoying your new year... I have a 27 gallon cube with a 5.5 gallon sump.. filter sock, carbon, chemi-pure, chaeto, protein skimmer for filtration... Without cause my water has started to get cloudy white.... I havent stirred up any of the sand or done any major work to the tank.. it just kind of happened when I woke up one day and it is progressively getting a little worse... I havent done any changes in water flow. I did a 5 gallon water change yesterday and it seemed to get a little better but then go back to the way it was. I wish it was a crazy amphipod outbreak that I could cure with a nice mandarin but my tank is only 6 months old and I rarely come across any at all... Any ideas???
