Help ID White Fuzz on Return Nozzle

[AquaDan]

Can someone tell me what this stuff on my return nozzle is? Looks like white mold. Is this something to be concerned about?

cant really see it, but it could be anything....

sponges growing the tank
carbon dosing build up

Thanks D. I tried to get a decent shot but its at a tough angle. I'm noticing buildup on all 4 return nozzles but its most abundant in the above pic. My parameters all appear to be in line except for my ALK which came in today at 6.8. Note sure why that is...

looks like salt creep, if its above water level.

I don't think its salt creep. Its underneath the water. Looks like some kind of mold I have no idea what it could be...

Hopefully these are a bit better. This is what it looks like when the pumps are off and the return is out of the water.

looks like sponge.... but it can also be a bacteria cluster as well.

Should I remove it?

i would.... looks like bacteria to me. Are you carbon dosing?

I'm running a BRS dual reactor with carbon and GFO. Should I be doing something else?

usually you would see that more often if you carbon dose. i would just keep up with your water changes and remove that stuff on your return
