Can HC Cuba thrive on inert substrate in a high-tech tank?

My Monte Carlo has been growing well even on an inert substrate, but I was wondering: would more demanding plants like HC Cuba still do well too, or is aquasoil really a big advantage there?

I’m about to transfer everything (fish, plants, filter, etc.) from one aquarium to another, and I’d like to avoid:

• ammonia spikes
• KH/parameter swings
• issues for the fish (I’ll be using an already mature filter)

Do you have any recommendations for a good inert substrate that is:

• easy to plant in
• doesn’t alter water parameters
• suitable even for demanding plants like HC Cuba?

Thanks!
