Plant in sililca sand?

[Petah]

Will it work? or will the plants die off?

Depends on your nutrients. I have plants in my sand and they are growing slowly, but well. I haven't really done any dosing of fertz either, just relying on the fish waste and adding some metricide.

I find the amazon swords and cryptocoryne do very well with some root tabs. I do dose fertilizers and liquid CO2. So to answer your question: yes, plant in silica sand is doable. I'm using black silica sand.

Plants can do very well in silica PFS, even in a low tech environment, with just a moderate level of liquid ferts and root tabs, like mine is below - so you can see for yourself:
