#1 Okay....I was inspecting my tank and notice a new growth. Under several pieces of live rock are these white cotton looking fuzzy growths. They are about the diameter of a pencil and about 1/2 inch long. does any one know what these are...are they okay???

#2 ALSO..Thre are these clear very small circular object on teh glass of my tank. Inside these flat bubbles are several tiny round yellowish brown round things....I assume they are snail eggs since the last time I saw them we had baby snails several day later....

#1 is a type of harmless worm, I think. Both are a sign that things are going good w/your tank.

those are sponges, and they are great filterers
