    Can't see too clearly, is it growing on the underside of the rock? Most probably just some type of sponge.

    hi,

    its the thin white strands in middle right hand side of the rock. it is growing mostly on the bottom of my LR but the LR in the pic is facing upwards and get direct light. if it is sponge is this a good or bad thing? also i noticed a rapid growth of these sand-like structures on the LR and in the sand with fine worm like creatures. I find they grow by two per week. what could it be and is it good once again?

    thanks alot for the help?

    Generally most sponges are very good as they continuously filter water, although you do get a couple of bad ones, like the encrusting blue sponge. Your worms and other creatures are making their homes out of sand, all good things going on. :)
