Cryptic Sponge & Sea Squirt Filtration Methodology

Cryptic Zone Hospital

After 16 hours in the unlit mud / cryptic zone refugium, Chilli is looking good under old macro refugium bulbs.

Chilli update

After nearly 48hour in cryptic zone refugium, Chilli's color has gone from maroon to a vibrant red, as he was in shipping bag.

Due to continued sand bed maintenance, detritus continues to be stirred up. Not good for Chilli. Chilli stays down under for another week.

Chilli might think its cool in the cryptic zone & might like to make it his home?
 
Just started on a cryptic zone sump design.

Have built a permeable dividing wall - semi cryptic/cryptic zones

Made from coral rock, coral gravel, white cement & rocksalt.

Maybe for a short time of < 3 months. By then my algae feeding platform will have filled in providing the shade that Chilli requires. Also, my sand bed maintenance should be completed eliminating particulates clogging up Chilli's feathers.
 
Exposed sponges tend to be very distinctive. Its relatively easy to tell the
difference. Unfortunately, most of the sponges that have been historically
offered for sale in the hobby are from exposed zones. These sponges do not
survive well in cryptic habitats. In general, if a sponge grows out of a rock
that is held in a cryptic zone, chances are real good it is a cryptic sponge.
Exposed sponges need strong current flows and some need light. Also, sponges
growing under corals tend to be semi-cryptic.

Hi steve, I've read cmat vol 1 & 2, at least the parts that apply to what I'm attempting to do. I'm using a permeable coral rock dividing wall to seperate a semi cryptic / cryptic zone in my sump. I was planning to slightly illuminate the semi section.

My problem is I have no access to dedicated cryptic sponge rock.
The best I can do is to use some rock from within my display that has sponge life on it to seed the cryptic zone. These sponges get zero direct light, but some indirect illumination. Will these sponges be ok or not?

I don't want tp place them in a cryptic zone only for them to die & possible pollute the system. Should I perhaps just make the sump fully semi cryptic??

cheers
 
Twin,
I feel that my mud cryptic refugium is semi-cryptic because the whole back of stand is open to air flow and ambient light.

I have also included a 3G chaeto refugium in display tank overflow box. I figure the production of DOC and micro algae, a type of phytoplankton.

“Marine phytoplankton are mainly composed of micro algae known as dinoflagellates and diatoms, though other algae and cynobacteria can be present”.
 
Day one of taking down the cryptic... its composed of three layers and sits in the middle of my sump.

The topmost layer is the algae zone. It's made of eggcrate and nylon mesh (like used for ATS). The water mostly flows over this zone from end to end

The second layer creates a baffle zone between the algae zone and the deep zone. Again- eggcrate and mesh. This channels any remaining medium flow to the other end but allows some exchange into the lowest zone.

The last layer is made up of 2quart buckets of sand/mud. Two layers of these buckets separated by eggcrate and mesh.

In this lowest zone, water trickles through the surface layers but does so slowly.

Today, I removed the first two zones...

Here's what I found.. fast zones have feather dusters... thousands clumped together to make "rock"...

In the top eggcrate squares, sand collected forming tiny sand beds protected from flow. These had.... tiny sea cucumbers! Less than 3/4" long! They we so small I thought they were sponges.

Lower down ... three kinds of sponges... first white, then yellow, then on the bottom pinkish purple?. These aren't "attractive" sponges. They look like wet napkin paper with holes and striations. Inside and around them are tiny serpent stars..

I haven't gotten to the buckets but here are the pics:

Ok. Last layer.. the very low flow sand/mud buckets. Here's the view before removing anything

There's a layer of muddy silt covering the bucket tops and the feather duster clusters are solid chunks here
 
The surface has a thin layer of sponge with raised bumps

Some we white or pink
 
This one was much thicker and yellow

Where the flow was higher, sponges gave way to worms

<a href="http://s1062.photobucket.com/user/karimwassef/media/BDB7FD38-002B-41E1-B2CB-7508EACE0C1F_zpsdssw7kjo.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/BDB7FD38-002B-41E1-B2CB-7508EACE0C1F_zpsdssw7kjo.jpg" border="0" alt=" photo BDB7FD38-002B-41E1-B2CB-7508EACE0C1F_zpsdssw7kjo.jpg"></a>
 
The eggcrate between layers had some impressive sponge growth

I'm inclined to believe that eggcrate is an ideal sponge habitat

That was about 6" long
 
Literally a birdsnest of worms

And more sponges

I wonder if these can be cultivated and shared... maybe a beehive like eggcrate structure...
 
I used different substrates in each of the different 18 buckets... basically a shotgun approach.

3 had miracle mud
3 had fine sand
4 had sugar size sand
4 had coarse sand
4 had gravel

I didn't correct better data than that :)

I take it the sands were all from coral?
