RDSB or not

Oh that's right, the 75g tanks only have 12" of width don't they. I have this really abnormal dimensioned tank sitting in my garage that is shorter and taller than what I thought you would be using (48x18), but that would be a 90 gallon.

Just thought it might fit your application better

My 75 gallon measures 48"L x 18"W x 21"T.

 

[jdavid]

And that's the same width as your 40 long??? Now I know for a fact 40 longs are 12" wide. Now you're just messing with me lol

 

[ghbrewer]

Sorry, I sometimes swap around width and length, my 40 long is 48"L x 13"W x 16T. Just picked it up from Rich.

They are both 48" long.

Gotcha. You mainly want to house anaerobic bacteria, right? If so, I'm with you, and I may try to do something similar but I only have a 24x24" cube so I'm pretty limited on space..

 

[ghbrewer]

Precisely, I want to promote as much anaerobic conditions as possible. I want to incorporate conversion, in addition to nutrient export.

 

[jdavid]

Makes perfect sense. Now I'll back off and let someone who may be more experienced tell us why this may or may not be a good idea. I'd like to know as well

 

[ghbrewer]

Anyone else have any thoughts?

Interesting discussion. I am considering re configuring my refugium concept. I think a 6" dark DSB flowing into cheto and mangrove would be nice. I have a basement sump so space is not a worry.

Great link, I came across it when researching, good read.

Yeah, space isn't really an issue for me as well (having a dedicated sump room planned for my basement remodel). I really feel that a dark Remote DSB (or "Cryptic RDSB" as I have heard it called), with Chaeto in a separate container (such as in a chamber in the sump) is the way to go (room permitting). The RDSB and Chaeto need to be treated differently. Both require a good amount of flow, but in the RDSB you don't want flow patterns that keep the detritus and particulates afloat, you want them to be able to settle on the bed for the critters and chemistry to work effectively. With Chaeto, you want it to have good flow too, but you want the flow patterns setup so as to keep it tumbling/rolling. it really seems that having them separated like this will allow each system to work more efficiently and effectively.

At my office, I have the typical configuration of Chaeto rock in the middle refugium section of my sump. While it seems to work well, I really think this other configuration will provide further benefit.

We'll see.....

I haven't really heard many downsides to this configuration, so I am still planning on incorporating it into my build. Maybe others will be able to provide more insight.

I spoke with another member (Skeet) at the meeting on Saturday, who had a configuration such as this on his large tank for years. He said that it worked so well that his skimmer quit producing skimmate over time. He said that he liked it so much that he is intending on running three 6" deep RBSDs with his new setup. I am not sure that all will have the same results, but as they say.... the proof is in the pudding.

Hoping to hear some more success (or failures) stories from some other members......

 

[ghbrewer]

I am going to add a poll to this thread to try and get some feedback. I haven't tried or seen this work before, so this may be a learning experience...LOL

Edit: Poll added to thread!

Not sure if it is viewable/accessible in Tapatalk though.

i will try ......whit calcium carbonate, 1 millimeter thickness.

Aragonite sand (what a typical DSB is comprised of), is already a carbonate material. Not sure if adding the additional calcium carbonate will add any more buffer capacity or actively maintain Ca, Alk, or Mg. Something interesting to consider, but there are already other proven means to maintain these parameters. I would just consider the DSB to function as a means of nitrate/nutrient control.

Ok......Tonight star RDSB in my compartment 20x20x25 (centimeters) with 6" of Calcium Carbonate, and insert one live rock for help to popolate my sand.

Nice! Look forward to hearing how it works out!!

Starter my RDSB, i have insert sand in my sump, 13 centimeters (calcium carbonate).....

1) isolate Tank from the sump....
2) insert Sand in sump and i have used external filter, for remove dust.
3 )insert bacteria.
4) after 3 hours ( after the water had become transparent) i have switch on pump for go back water in tank.

First problem....nitrites 0,5.......used vodka and bacteria, after 6 hours nitrites 0,2......
