Well it all depends on the oxygen saturation in your tank

If the saturation is high, you might need a thicker DSB to restrict diffusion

Remember, you want to achieve a lowly oxygenated area

[shoelevy]

i think adding around 10-20kg isnt too expensive right? costs only $6 per 10kg..

ah...with 120kg i reach only 8cm....means i need another 30 to reach 10cm...tired washing and no money....

how do i measure my oxygen saturation?

[shoelevy]

actually...any thicker sand bed and my tank will look ugly

[DragonGoby]

Depends on the grade of sand you use as well - I suppose you could get away with a thinner sandbed if you're using really fine sand, #0 or oolitic for example.

i'm using#1 sand....any problems with the dsb made of this sand?

nxt time you can use coarse sand on the bottom put a layer of net and then add your fine sand.... but since most of your sand is in....

juz a suggestion

Bro, scoop the sand in front to the back, so that in front u have about 2.5-3 inch of sand, behing about 4-4.5 inch, should be better that way...

steal it from one of the beaches loh...hahahhaa

i think its better to have a very thick sandbed...i never regret having a 5inch DSB cos now i have no Nitrate problems at all..even though i feed my tangs like mad(3-4times a day)...

if u only have a 3inches DSB, i rather u save the money on the sand and go for a big skimmer...but since now tat u have already have the 3inches, then add more loh...

bite the bullet when u are setting up..its better than regretting it next time when u face problems...u will hate it!!

Hi. No nitrate problems? I assume it is below 5ppm or perhaps even zero?

That's great!

Could you kindly share with us more info about your DSB?

What sand type/quality (#0 or #1 or mix) did you use?

Is it 5" evenly distributed throughout or sloping?

Is the DSB in your main tank or sump?

What size is your tank or sump?

How many KG of each type of sand did you use?

How old is the DSB now?

Thanks very much for sharing.

For DSB to work you need a minimum of at least 3 " any less will do more harm (nitrates) than good. A good DSB is 5-6".

If you have a refugium for nitrate export, then it is not necessary to have a DSB, you way want 1/2" to 3/4" for "looks" purpose where you can clean the sand bed easily.

i dun have any special method...just 5inches of grade zero sand in my main tank...

I have a sandbed of 3.5 inches thick and have no nitrate readings too
