i have recently had a spate of growth from what can only be descibed as spiderweb looking algae/coral/stuff. its opaque/seethrough and is getting larger. it is sprouting up all over my live rock. its not 'taking over' my tank, but just want to make sure that this isnt going to get out of hand. i can only presume that its a bit of over feeding maybe or the tank is going through a cycle.
please someone put my mind at rest to what it is and if i need to take action
thanks in advance
