I have a Nano Wave 9 AIO that I purchased used from someone a few months ago. At first, I had it set up with everything they had-including the rocks with bubble algae, aiptasia, etc. After some time I got sick of it, so my fiance and I put all the live stock in the big tank, and completely cleaned the nano out and soaked it in vinegar. It's very clean now, and right now only has the sand in it that was washed very throughly. It looks brighter than it ever has. However, I'm getting a lot of micro bubbles from the skimmer in the display, causing it to look cloudy. Any suggestions on how to fix this? I'll put pics up of the clean tank tonight.
