Hi all!

Can you please let me know which substrate out there is the lightest in colour? not sure if there is a white one...

Onyx comes in red
EcoComplete is dark

also, can i use crushed marble as a substrate??

AaronT

Onyx is grey. That is probably one of the lightest colored substrates.

jho51e

does grey look better aesthetically or black (ecocomplete)?

I have used pool sand which is a tan color, some brands come in white.

jho51e

and do you just use the pool sand or do you use this as a top up for something else underneath?

trenac

I used First Layer Pure Laterite underneath the sand.

Thanks trenac... now let me find laterite here in aust...

trenac

If not, maybe you can find something similar. I also use Seachem root tabs for extra root nutrition. not pool sand

Let me clarify my previous post... I use Pool filter sand,not pool sand. There may be a difference.

jho51e

found it, so laterite is a fertiliser?

trenac

Glad you found it... It's a clay, something like flourite, that provides nutrients to the plant roots.
