Inline RDSB

So I have a closed loop system running 3 of the 10"x2.5" canisters right now. One has BP, one has Carbon and GFO, and one has floss. I'm adding a second set of canisters, I was thinking of using a 20"x2.5" canister with 3/4" fittings to make a DSB chamber. Flow rate would be around 250-300GPH on this side of the loop, plan would be to fill the canister to about 15" with sand.

 

Canisters:

Current:

Pump

Canister 1: Floss

Canister 2: GFO/Carbon

Canister 3: Biopellets

return line

 

Planned would be:

Pump --> Loop 1

--> Loop 2

 

With Loop 1 becoming:

Canister 1: Floss

Canister 2: macro algae

Canister 3: Biopellets

 

With Loop 2 being:

Canister 1: Floss

Canister 2: Carbon/GFO

Canister 3: RDSB in 20" canister.

 

Both loops would then feed back to tank.

 

Thoughts? Stupid idea? Worth trying?

What are you trying to gain by doing this? Do you have an issue with nutrients? If you aren't having any issues I feel like you may be spending money for no benefit.

I find the gfo portion and the sandbed portion to be opposing, the gfo is picking up the waste that the sb is collecting and leaking back.

 

agreed the intention is to get nnr, but I think one could set up 20 true dsbs, like what you are doing, and get only 1 to reduce and then set up 20 more and none reduce, its a low ratio crapshoot to get NNR. NNR was one of the biggest myths perpetuated in reefing, that live rock and live sand reduce nitrates (they catch detritus and produce it, rather)

 

the stories were made from the 1 offs that worked.

 

there is no harm in setting up this experiment as any of the nodes are easily changed, cleaned, removed, all harmless predictions here.
