I have a nano tank that's been up and running for about a year now. The water started getting slightly cloudy about a week or two ago, so we tested the water and did a water change. Water cleared up for a few days and then started getting cloudy again. Then, we woke up to find that our wavemaker got clogged up throughout the night and the water was so cloudy that we couldn't see anything in the tank. We immediately started moving all livestock into our QT tank. We tested the water again and removed 3/4 of it and replaced it with fresh saltwater. DT tank has been running for 48 hours now with no livestock and it's crystal clear. Now our QT tank is cloudy. Wavemaker has been running the whole time. We have two clowns and three hermit crabs. We've experienced bacterial blooms in the past, and we increased surface agitation with an additional wavemaker and increased filter density by adding polishing pads. During the bacterial bloom our clowns would gasp and seem stressed, but with whatever is happening now, it doesn't seem to be affecting them. Help! I'm at a loss. I'm so thankful that we haven't lost any livestock during this.
