Hi, I'm trying to create a riverbed scape. Not a biotope at all but just a nice riverbed scene to look at.
This is the hardscape so far.



I've created the height with Oase Scapersoil in media bags in the area marked red (2 high along the back - maybe a bit wasteful). I've used a egg crate/plast grid underneath the main hardscape area to protect the bottom of the tank (which is a 60x40x40). This is just covered in riverbed sand with the plan to plant into the sand and the roots hopefully grow into the media bags. The sand at the back is approx 4"/10cmish.

Would you say that's too deep/wasteful of tank space?
I starred scattering some of the smaller detail river gravel but I don't want to pull the trigger on this and then regret it so thought I'd stop and get some critique/advice on the hardscape which would be very welcome.
Thanks
