DSB sandbed for my 2 feet cube tank

[andysho]

Like to have some of your advice and comments

on how much of sand and grade should i use for my upcoming

2 feet cube tank

thanks bros.......

If going for 2ftx2ft and you want 6" DSB with grade 0 then need about 80kg.

i was told by some reefer~~`

bottom cover with 30kg of grade 5, cover by 30 kg of grade 0 which is use as the top sandbed

another one old Lfs tell me that by using grade 0 on top..will trap bubbles in the sand~~` and in the long run it will be hard to maintain as the 0 sand will stick together

very confuse leh....which one to use kekeke

[weileong]

I oso not sure but I followed the advise of one super senior reefer here advise me to use 4" grade 0 as based then 1 or 2" grade one on top. Then add a mesh on the grade 0 sand to prevent things from digging into the DSB.

[andysho]

yours seems to be a great idea to add a mesh over it~~

kekeke

welcome more comments and advise

Yeah but bristleworm still dig 5" into the DSB but small one.

i guess more ppl use sand 0 on the top because it look very natural with a fine white grain sandy effect

The effectiveness of DSB do not simply lie in the depth of it, but also the surface area for it to work on.

If your objective for the DSB is for denitrification purposes, you can also consider doing regular water change for nutrient export (NO3 included) instead since your water volume is relatively small.

DSB in a 2ft cube take up valuable estate, not as eye pleasing, and may hide Hydrogen Sulphide pockets if not managed by sufficient sand fauna.

what do you mean by

"and may hide Hydrogen Sulphide pockets if not managed by sufficient sand fauna."

can i said again that most of the reefer use grade 0 or 1 on the top for the so call fine white grain sand effect instead of considering using

grade 3 which tend to lose out in viewing purpose

Assuming you have done your reading, you should be aware that running a DSB has its pros and cons.

Nonethless, here's the link to the definitive guide by Dr. Ron Shimek.
