Ok so I googled this and the 2 most common results are that it's expelling zooxanthella and or poopin. Has me worried as I've never seen it do this in the 4 months I've had it. I haven't changed lighting intensity or moved it recently. I just added a Royal Gramma that's taken up residence nearby and has kicked up some sand around the torch. That's the only change I can account for. Any input is greatly appreciated. Thx
