Nice array to products hydrophyte. Ever since I saw this I wanted to try one, but right now my tanks are in mid maturity and don't have room for more, so I'll have to wait before I change one to riparium.
I have been toying with idea of "Nature Riparium" like Nature aquarium. That would be pretty cool given that, with more plants growing outside water, the issues of CO2 injection and algae are greatly reduced.
The only issue I am trying to overcome in my mind is how to soften the water line and make the submerged and emerged parts more cohesive in the "nature picture".
One idea is to lower the water level and have most plants grow emerged with a few foreground type plants grow underwater. The water can probably be used to highlight open space and mimick a lake or water edge. In nature aquariums people have used sand or bare tank bottoms to do the same. This might be a new way.
Also the famous sand waterfall nature aquascape can also be brilliantly replicated in riparium since you can have the filter outlet (with little modification) directly serving the purpose of waterfall and the water level below makes a natural pool. Personally I like this idea the most and probably would start with this one when I am ready.
Do you have information on any floating plants with fine leaves and paler leaf color? Thinking of a nature scape where these (if any) can work as floating clouds and can soften the water line for farout type scapes.
Anyways, these are just some ideas. Since you already have all the gear, maybe you can try doing one if you like them
