I need to hi-jack for a second. In the last photo there is some round pink'ish/purpleish growth on the rocks with round holes in the middle...What is this stuff?? I have some of the same but also grows in long stringy lengths...Seems to be some type of sponge

yeah he really hates the black cloth I put on the back of the tank for FTS. He wigs out in that corner practically the whole time I have it on, which is why sometimes the pics look like arse, cuz i'm trying to get the shot too quickly.

yep its a lower light sponge, the whitish type seems to get those long strings on them and after a few years if you try to separate your rocks you'll find they're glued together by the sponge. Kind of neat that it secures your rockwork for you but also annoying that there can be so much of it in there. I also have a couple of other sponges in the tank that come in pink and red, no strings but they look sort of the same as well as yellow ball sponges which are really neat :biggrin:

Perhaps the color is a bit diminished but your tank really great mature look to it. I've never had that wafer algae...call me nuts but it kinda looks cool?

it does kinda look cool but eventually covers every rock and gets to plague proportions. It also gives the tank a dull brown overcast which is less than attractive. I don't mind it in small patches but that never lasts long.

do we see a small naso in your near future?:wink:......or are you just gonna manually pluck it out?

naw I don't think I can do a naso unless they've made a dwarf version. Once the wafer algae starts to "plate" its easy to siphon out but I'm hoping the ultralith does the trick :biggrin:

Naso's stay small for a couple...............months:mrgreen:......I battled waffer algae too and the way I got rid of it, was a blonde......its a tough one to git rid of......hopefully your UNLS will knock it back....

LOL, yeah if I could remove one fairly easily I would definitely go for it but the thought of tearing the tank half apart to get it out after the job was done, frankly it makes me tired :razz:

Oh the other hand I'm currently looking for ideas for "natural" majano and aiptasia control, anyone had any experience with utiliensis butterflies?

uh ... hi?
