Well, I wanted to put Eco-complete in.. but none of the local shops had it :( So, I decided to go with the sand. It's from Carib sea - they also have an instant aquarium one with the same sand, except it has living sand (they put in blackwater or other microorganisms to make the cycling process easier)

I'm still doing more research on just how to care for a sand substrated tank. Kinda meh cause I just bought a gravel washer which is way too powerful for sand - so back to using my turkeybaster syphon ^.^
I don't have or want any trumpet snails... so, I'll need to agitate the sand here and there to prevent gas build up, yeah?
