Fairly new to reefing. Had a 55gal reef tank for 10 months and never had a single outbreak of anything. Woke up one morning and the glass had cracked. Now have a 100 gal tank and just finished setting it up. Found some live rock where I live and have been cycling my tank for a few days now. Yesterday a white slimy spider web looking substance showed up in a few of the ledges and today it is everywhere. Don’t think it’s a slime because in the video you can see part of it has been blown apart from my power head. Anyone know what it is and or what I need to do about it?
