Question about my rbta

[Jeeperz]

I have a rbta, it's the split from the parent that's in another tank. It has been in this tank for maybe 6 months. In the last week or so I've noticed a slime comming off it near the base of it's foot. Tonight I actually pulled some of this slime off before it let loose in the tank. I've also noticed the last few days my tank water is slightly cloudy but I also don't have carbon in the tank. Of course it is in a place I can't get a pic.

Has the nem been damaged at all? I would definitely throw some carbon in the tank and do a water change.

I've done several 12 gallon water changes the last week. Dkh 9, Cal 420, mag ~1350. Run roughly a cup of carbon(red Sea) by the skimmer intake in a bag, it's fresh. Nrm does not appear injured. It's moved around the tank a bunch and has so far settled at the same starting point, just below side weir on rsr350. Never seen any of my nems slime like this, it's like skin.
