I have two DSBs i cant cut the glass between them without digging up the DSB, someone said that they will fight for nutrient or something is this true and is it safe to have two DSBs?

My nitrates are on 1-2 so is there anything i must worry about?

And what can i do about my DT sand bed or must i take it out and replace it?

I've got 2 DSB's, a big one in my refugium and a small one hanging on the big refugium. Here's a pic.

And do you notice anything between them?

The big one is only running for 4 months now, there's a lot of worms and snails on the substrate. The small one is starting to get black at the bottom. I don't think that 2 DSB's can be bad, you're getting double the advantages of one.

Agree with Tobes, more diversity, and they are only going to compete for Nitrates/Nitrites, so thats great.

That is a great looking system you have Tobes, what benefits do you find with attaching the smaller one like that?

i think it might be better to have two.
if something was to go wrong in the 1st one(say it got stirred up) and you lost all
anerobic bacteria the second one will be able to repopulate the 1st one. just
my thought on it

When I bought this new tank, I had the small refugium attached to my sump inside the cupboard. Only later I decided to get a bigger refugium and attach the smaller one to it then I'll have more space inside my sump area - easier for maintenance.

Previous with small refugium in sump

and now without it

Didn't wanna pack the small refugium away, so decided to use it as well - might be beneficial ;)

Why would you want to replace your DT sand bed Ocean? I'll only advise you to replace it gradually if it is very coarse, unless you wanna go BB. ;)

Jason, I also have 2 DSB's Mainly due to the fact that my original sump was a kak design, I now have a 10cm aragonite DSB under the LR and a 15-17cm play sand DSB with chaeto - my nitrates/ites are awesomely low - so I guess its doing the biz. Apologies for the flash but sump is in the dark due to reverse lighting cycle

Tobes, dude, that is an awesome looking sump - what lighting you have above that baby? I have a green light, but due to PO4=0 I cannot grow algae excepy coralline - but man thats neat!

M, you make it sound like a bad think that you don't have algae ;)

The lights above my refugium are 6500k daylight energy savers from Lumaglo. I used those light fittings you get at Game for outside use. R30 each.
I then modified my unused Seio flow pump brackets to suspend the light holders above my refugium. :wave2:

AWESOME Tobes! Great sump, man!

Jason - yes - I too would live to know why you would like to remove the sand in your display tank? IF you want to go through with this, then you will need to increase the water flow inside your display tank as well - to ensure that you have around 80 times water turn-over - that is if you want to start simulating what Puppy has ;-)

BTW: the two DSBs are 100% fine. Will definitely be 100%.... So, don't worry about it!

BTW: Thanks for the linckia - it seems to be very happy in my tank :)

Warr, absolutely not - although my sailfin gets slightly pi$$ed that he has to eat nori and not the real thang - and I have been dying to get me a good mat of Chaeto.... but I will take the PO4-0 any day :)

On the whole I am happy with 2 DSB's - interesting thing is that I only seem to get the fanworms etc on the glass of DSB 1 - and DSB2 is a lot calmer - but after lights out it is full of 1-2mm long shrimps - so a good place for the quieter bunch I think
