I got this one SPS colony 2 weeks ago and it was sliming up a lot, so I moved it to the sand bed in a different area of the tank. It was fine then, but no PE yet. Still not much of PE, none on most branches but very little on a few branches. People told me to remove the foam filter intake on the return pump, so I did. Now you can tell there are more microbubbles in the tank and that colony is sliming a lot again. Would that be the cause of it? The extra microbubbles?
