I went to LFS just a while ago to order #1 corals sand , they told me that better to pour a layer of #5 corals stone at the bottom to create anaerobic environment . Any advise on this ?
For pouring sand in my tank size of 90*60 @ 3 cm height , they said I need 40 kgs (with some excess) , and also advise me to increase the glass L shape walls to 15 cm to block the sand from accumulating at my overflows base crate:
Below is my glass L shape wall with 5 cm height ;
Any advise ?

Just check with 青島水族館、they have coral sand number 1 , I will buy 40 kgs plus 6 kgs # 5 coral bones , is this ok?
By the way , how should I do it when bring it home , should I rinse only with RODI water then put It directly to my DT or should I have to cooked if with acid as people doing with their dried rock?
This are dry sands from corals and bone of corals , will they emit phosphate later ?
Want to hear your advise before I pick them up tomorrow .

the plan is to have only 2cm sand. I have no idea how to use both #5 and #1 sand the same place at the same time. and as for haveing anaerobic environment , my suggestion is not to use # 5 sand because you will have liverocks and the rock itself can do the same thing ( For SPS i think it is OK ,you wouldn't have a lot of fish ,right?) besides you also have bio pellet reactor. you really dont have to do the so-called DSB.
and the gap behind the L shape glass, I wiuld cut a piece of f black filter sponge to fill it.

So if only 2 cm then it needs how much qty of fine sands ? Will 40 kgs too much ? I don't want to buy much more than I need as it take up my house spaces to keep it .
They says number 5 coral bones place at the lower layer then on its top add the #1 fine sand , this is what the LFS say to me.
Infact I have 6 fish all are large fish : blue tang , powder blue tang, fox face, purple tang , and 2 others I forgot their name . I also suspect my tank is with high intensive fish population.
You mean the space between the LShape and false wall ? I am worry the it will float ?

Is the additional 1 cm meet the criteria of DSB? Is it normally DSB is about 4"-6" deep?

If you use #5 at the lower layer and #1 on top . that can't be a thin layer. probably you will need at least 5cm~6cm or more sand all together. am I right? I believe it is also a good sand base even better than just thin fine sand. However ,I haven't got this I am not able tell you if it is good for you. maybe someone else who have experience of this can give a comment and advise.
And yes the sponge will float .I forgot. maybe the bigger grain size sand will do.
