That's an awful lot of aquarium plants and if you would like to see how it's done, you'll enjoy this video below from Aquafleur in Holland. I'd also recommend having a look at MD Fish Tanks on Youtube as he's creates a lot of content with some lovely set ups. UK based too so it makes a nice change.
