Renovate my Cleanup Crew?

Myka

Reefing since '93
I am noticing quite a bit of detritus buildup, and grey stringy crap hangin out on my sand. I don't think it's getting cleaned well enough. My cleanup crew is keeping the LR and glass nicely cleaned, but the sand I think needs something more. I don't want anything that will depleat my sand of life (I hear starfish do that). Can you guys please suggest a/some critter(s) for me?

In my 33g tank I have mostly snails:

3 Stomatella
3 Astraea
3 Cerith (the big grey ones)
2 Turbos
2 Margaritas
2 Nassarius
1 Hermit
 
I don't want the hermits to kill my snails, but he does dig through the detritus a lot. The only reason I have that one hermit is because he came in on the shipment that was supposed to be 3 Nassarius, but he came with the Nassarius shell.

What if I added more Nassarius or Cerith? They both hang out under the sandbed a lot. Or a shrimp of some kind? What about a cucumber?
 
FYI Most "sand sifting stars" usually spend most if not all of their time hiding under a favorite rock, they usually do very little sifting. A cuc does a great job, but most can get pretty big, and you always have the risk of it nuking your tank if it gets startled or dies. Make sure it is a sifting cuc too, cause some are filtering. How about a good sand sifting fish? Or a conch?

I would go for some Ceriths since they perform doubly duty and will clean the sandbed and well as your rocks and glass. Thoguh I don't think that's the answer to your problems. You probably need more flow to make sure the detritus isn't settling in the bottom of your tank.
 
Thanks everyone!!!

I do have a Yasha Goby in QT right now. He has another 2 1/2 weeks in there before he'll be making the display his home. I think Yasha Gobies are sand sifters...??? Maybe once he's in there he'll clean it up better. I'll be getting a pistol for him as well. He was supposed to come with a pistol when I ordered him, but they were out so they just sent me the Goby (I was not impressed, but they gave me a killer price cut on the Goby to shut me up).

As far as flow goes, I'll try to describe my set up as good as possible. I have all my LR piled up in a line along the centre of the tank (in other words it doesn't lean against the glass anywhere other than the bottom of the tank).

I have two Maxi Jet 1200s (295 gph each) attached to my Wavemaster Pro. The PH on the left is positioned on the glass so that the output is pretty much dead centre height-wise and blows along the back of the LR. It's flow also reaches the sand along the back of the tank and keeps it free of detritus back there. The PH on the right is positioned so the output is about 3" from the water surface and is pointed at an angle towards the water surface, but also towards the back pane of glass. The way I have the powerheads set up right now is the only way I have been able to set them BOTH up at the same time without disturbing the expansion of my LPS and softie corals. Any other way I have tried to position the PHs has caused too much flow which makes it so my Xenia won't pulse, and my bubble coral won't expand all the way. The way they are positioned blows all the detritus to the front of the tank which is unsightly, but easy to siphon out during waterchanges.

So maybe I need to get 3 or 4 smaller Maxi-Jets? Maybe MJ400s? That way I'd be able to position a couple along the front to blow the detritus away there too and hopefully keep it suspended then...? However, I am concerned that even the MJ400s in such a small tank would bother my LPS being so close to them.

As far as pods go...I have a TONNE of them right now! I have been feeding my tank regularly with DT's Phyto and their population has exploded. I was thinking about the cucumbers...I am a bit worried about it dying though! I am told that my tank is too small for even the small conchs; that one would eventually starve in my tank. Thoughts? I have researched the Cleaner Shrimp and am undecided...I have read that they are hit or miss when it comes to bothering corals.

Also, I do not want a DSB. The tank is small enough as it is, I can't be using up more gallons with sand... or are you just suggesting that I should make use of the sandbed critters that are used in DSBs??
 
I love my cuce, he just eats the dirt and poops piles of clean sand

as much as we stare at our tanks, i will notice if he is dieing of if multiple things are closed, I start checking around
 
Usually DSBs have the problem you are describing so I "assumed" you have a DSB. Sorry about that. :(

A shallow sand bed IMO should never accumulate detritus because you can put as much flow, stir it yourself, or siphon it to keep it clean. You can blow it around and disturb it as much as you want. A DSB, totaly different matter.

You didn't say if you are running skimmer or any kind of mechancial filtration and if you did I missed it and I apologize.

Right now you have roughly 17X turnover. In the grand scheme of things that really isn't that much flow, even for softies. I have 50x in my SPS dominate tank and my xenia is happy getting pummeled by the 1100gph return from my sump. That's not counting the 4 other power heads I have in there.

Knowing what I know now you simply need more flow and better mechanical filtration. If your concerned about over doing the flow, then start with mechanical filtration. A 100 micron filter sock does wonders. :)
 
My signature has all my equipment listed. :) My skimmer is a Remora HOB (run by an MJ1200), and I have an AquaClear 200 (200 gph) on there as well. The AC is turned as low as it will go because I have some Phos Guard in there right now, and it's main purpose is to hold a sponge for when the QT needs to be used.

Maybe the Xenia will get used to a higher flow? I just noticed that it pulses like crazy when it's in as low flow as I can find for it on the top of my rocks (at the top of the rocks hopefully to keep spreading to a minimum). If I move it into stronger flow it stops pulsing and gets "stringy" looking.

Maybe I'm a wuss...maybe I just need to be tougher on my corals? Maybe I just need to add a MJ400 (keep the current MJ1200s) blowing on the front of the LR...?

From my understanding my Fox, Bubble, and Open Brain all need to be kept out of strong flow don't they?
