How long did something like that take to build up?

that's crazy. i thought those brown tube worms you have on the outside of the skimmer were in everyone's system but i don't have a single one growing anywhere in mine. i've always had them in previous setups i wonder why.

I think the last time I cleaned out my skimmer was a little over a year ago.

I was just thinking this. I actually got up to go check after seeing those photos. Nothing in my sump or skimmers. I do have one singular XXL feather duster in my sump, but nothing has changed with it in over a year.

i only have a few of the white ones too. all i seem to get are those annoying 1/4" ones that stick out and make all your live rock look like a pincushion. never see any signs that they're alive until i baste my rocks then they throw out their nets.

He'll if anyone wants those feather dusters I have thousands lol same as mine they attach to every darn thing lol

I also have boulder sized rocks and branch rock
covered every inch in yellow sponge good for someone who wants a quick start :)

Woah...that a lot of feather duster worms. :mrgreen:

I think what this amounts to (aside from a butt load of dusters) is the fact that my tank is probably a cesspool of dissolved and particulate organics which the dusters thrive on. Perhaps your tanks are actually clean :biggrin:

lol well you tank looks good so somthing is working

Guy. I don't want to know. If that was my skimmer I would have chucked it and fired up a new one rather than clean that....thing. Just saying.:behindsofa:
