Are you carbon dosing? The strings look like those in my sump and on the glass when I was doing that. Otherwise, that's dino's. I'm afraid that adding chemicals probably won't help. There are many good threads here about the problem.

dino's i am very sorry for you. almost tore my tank down because of these. was a long battle i am afraid. stop doing water changes. they thrive on the new minerals in new salt water. also try and bump your ph up to 8.6 for awhile. good luck

Increase the flow on those BNs.

Same problem here with my pink birdsnest. get your nutrients really low and do a day or 2 without lights. i get dynos every six monts or so when i feed too much. I also stick filter socks on my pumps in the tank to clean out all the algae when it dies from leaving the lights off. good luck.

Are you running phosban? If not I would recommend it.

You should also drip kalkwasser to try to get your ph to 8.5-8.6. I would not trust a test kit, you will need an electronic ph monitor.
