    If it were me... I'd just turn the skimmer off... but it's hard to selectively grow sponges without growing algae and everything else. Hmm... maybe if you had a remote refugium in total darkness... that might work.

    Yes a remote tank that is kept in total darkness and the you put egg crate in it, something like a bee hive. They do this to make a sponge filter.

    Oh right... the egg crate! Thanks, I forgot about that... this is how I "accidently" learned how to grow sponges actually. I was trying to grow macroalgae, but my light died and I ended up in sponge-ville. I'm pretty sure you could use any matrix of surface area... acrylic sheddings too I imagine. Sponges seem a lot less picky about what they'll attach to than do seem a lot of macroalgaes...

    White hairy sponges grow "Automagically" in the "dark" (cryptic) zones of my tank's sump...... I have hundreds of them in there.....

    yeah i had a lot too. i was pretty proud of my sponges thinkin the angel would be happy for a while but he cleaned it in a day so that didn't quite work. ok so how about this. i build a refugium and put sheeting to make it dark inside, and have multiple egg crates. and then maybe move a sheet over to the tank every week or so depending on how fast they grow? can i take sponges locally to start it off? it legal? and any idea which sponges would be good to use if my little white ones can't grow fast enough? how fast do they grow?

    turning the skimmer off isn't an option cause of my bio load, but i have another high phosphte tank which could be used. so they would prefer higher nutrient levels, is that correct? what are the optimum conditions?

    Ok, been thinking about this and i am able to set up a dark tank for sponge growth only. I am thinking a lot of racks of eggcrate(either horizontal or vertical) for the sponges to grow, what kind of flow in the tank is best? i have figured out a rotation of each crate i pull out to feed so that they each have the same time to regenerate, how long does a typical sponge take to grow in optimun conditions? I also remembered seeing somewhere that when sponges die in a system they can really mess up everything, this right? If so i was thinking of making the 'cycle' of crates going in and out for feeding quicker(as in one every two days instead of one a week for example) so the sponges do not have a long time to grow enourmous, rather a lot of smaller ones than the same number of bigger ones. Cause if the angels take a bite out only for example, it could still irritate the sponge into releasing nasties into the water so i would rather it dissapeared in one bite rather than be pissed and foul my water. that way if the angels arent that interested what ever isnt eaten is still intact. Any views on this? And it would act like an algae scrubber in the sense that they are being 'cleaned' off the eggcrate as you would your algae and would then consume more nutrients to regenerate, like trimming chaeto. So it means i'm not exactly wasting the equivalent of algae where int his case the sponges go back into the system as food. so it kind of helps out my water quality(if i have enough sponges-assuming no real fouling of my water) and feeds my angels and keeps them off my corals. Cause today i saw the bicolour following the rock beauty and copying it, and they also seem to be interested in something on the side of my large pin cushion. so i'm hoping this works or i'm gonna end up making this i FOWLR:lol:

    I would keep the water flow moderate. You want enough flow to keep the water moving, but not too much. Sponges can move water through themselves (i.e. in a way, create their own micro water flow).

    The return flows might be enough. If not, a maxijet should do it. As for the kind of sponges, I'm not sure you'll be able to easily pic and choose. I would just let grow whatever grows...
