Mix or layer 2 types of sand

[User]

Hi All

Finally getting to scaping my in wall 180. I’ve got 120lb of CaribSea seaflor special grade and 80lb of Fiji pink coming tomorrow.

Question- after rinsing, should I mix together then put in tank, or layer it? If I layer, which goes down first?

Thanks

IMO. Either.
If you want pink on top or white. Or don’t care.
