Hi! I have had my tank setup for approximately 4 months, and I have started noticing web like stuff on my substrate. I added a couple of nassaarius snails and that is when I began noticing the webs, so I began thinking maybe they are coming from the sand and the snails are bringing them up to the surface? I read about vermetid snails however I cannot find any in my tank. The webbing is found on the majority of the substrate but there is none on my live rock. Any ideas? Should I be worried?
