I picked up a 2 year old Red Sea Reefer 350 with accessories. I have cleaned all the coralline off of the display tank glass. I am now cleaning sump and overflow which are fully encrusted with these dried up sponges and white worms. I Does anyone know what they are? I will clean with vinegar to remove, but I want to be sure that they can’t come back. They really took over the sump and overflow and I don’t want them in the tank once I get it set up.
