Thank you, we'll check it out! :biggrin:

My skimmer is working now! It's starting to produce a small amount of skimmate...

I'm trying to get a good picture of these things growing on my rock. They seem to get bigger every day. They are like tiny white branches coming out of the rock. I have a handful of feather duster worms... these are not the same... they don't retract, or move... they just sit there. Very small, fine, white branches. I will try to get a good picture soon, but do you have any idea what they could be?
