SUBSTRATE QUESTION

[camsfishtanks]

Hi all, Just watched a recent aquarium co op video titled: ‘whats new in the fish room? Unveiling latest changes’ and at around 2:06 cory shows a tank I included below. Anyway, I am curious what the substrate is? I know it must be some sort of sand, but I would assume it is more course and mixed with something else? I am rescaping my tank and am looking for a sand that can be used with both plants and corydoras. Cory, If you happen to see this could you tell me? or if anyone else knows or has recommendations?

if i was to guess, its probably mostly crushed coral.

The co-op does have their own sand they sell in the store. This may have changed, but essentially it is similar to lapis lustre sans which is now no longer available due to sourcing concerns and environmental damage.  It was sold at hardware stores and it's been a major issue in California where the sand originated.

Anyways, if you're looking for something similar..

Caribsea Carolina Creek, torpedo beach, or Crystal River would all be extremely similar in size and work well.
