Difference between using difference sanded

[tijou]

Hi reefers..may I know what is the difference between using normal seasand(white) and those "black and white" sand used by some shops in their display tank?

I would say its mostly personal preference

Not sure what is different best ask the shop sales person

Appearances..depend on what u like to see..

White will make the whole tank brighter. Read somewhere saying the good thing about white sand is they can reflect the light so can benefit corals. Not sure if it is true

[tofubox]

Lol, i would say its to a very small degree. Unless u are running BB, than yes, the reflection will be much higher.

Thanks for the advice but I realized it's hard to maintain on white sand..especially brown algae start to grow..

If brown algae start to grow on sand bed, it mean not enough flow or improper flow..

If you're referring to aragonite (light coloured, whitish brown sand), then it could serve as a buffer too.
