I've been noticing a lot of Yellow sponges all over the place on my tank, My question, Is that a good sign of things heading the right direction or is just a pest??
excessive sponge growth is a sign I use to determine if I have alot of nutriants in my water even though I don't have the unwanted algae growth...some is OK, but alot is a bad sign because they are feeding of something in the water....JMO
