Coral Sand for Marine/ Reef tank setup

[Clownfish]

U mean that the nitrate may increase overnite even if I tested the level is 0ppm initially?

i think it may be possible there may be some chemicals present in the tap water that gave a false reading?

Refer to

and goto water quality....

Tap water is nv guaranteed to be 0mg/l

Interesting, Barracuda! You'll be the first in SRC to try use glass beads for DSB! Just make sure you don't get sandsifting gobies... or you'll find a gruesome mess of blood later.. LOL... kidding!

Let us know how it turns out okie? Probably half a year later?

Actually I have samples of crushed glass and glass beads with me. Both are of similar size but the crushed glass is very rough and pricky to touch whereas the glass beads are very smooth to touch. Maybe I should get a cuke to see if it will get internal bleeding

if all you want is 1kg, no probelm ... I can give you FOC.

The glass beads are transparent but when they are so fine and dense, they appear to be white. Glass does not absorb phosphate, heavy metals or any other compounds unlike coral sand. It is also inert meaning they wont react with any chemicals and break down to glass powder. The only disadvantage is the price .. it cost $1.4/kg. My tank of 4x2.5 will need 3 packs (75kg) to have a 4 inch sandbed.

Thks a lot!

Where u stay? I stay in east area!

just wondering... using coral sand as DSB not only for ntrifying proccess but it also helps to maintain/buffer the PH level? although it can't increase/maintain to PH8.3, i think it does help a bit? pls advise.

its not significant as coral sand requires pH 6.5 or below to dissolve. Pple wont be dosing kalk or buffer to raise their kH if their 100kg DSB can do it for them.

The theory that coral sand will buffer the water is only true in fresh water aquarium

[lyz77]

Looks familiar!!!

Maybe saw it in one of the LFS! But can't tell whether it is white gravel or glass?!

[BarraCudaTM]

I dont know what is it but mine is very fine .. quite impossible to take photos with a normal camera.

Revived this thread.

Barracuda, have you changed from C0 to glass beads yet? I tempted to use them.

[BarraCudaTM]

Not yet .. my tank is not ready
