Here is the earlier question: Hey guys! I was wondering if anyone has experienced what appears to be spiderwebs growing on live rock? I have not recently added any new live rock, just 2pcs of white coral and green macro algae. Ammonia is 0, Nitrates and Nitrites at 0, temp 78 & salinity .023. What is causing this? Inverts and fish are just fine. Thanks! Just remembered, this problem did not arise until I started using the biofilter and carbon. Could this be the problem?
