So i created a sandbox aquarium to play around with hardscaping, much more complicated than I originally thought, the sandbox is one of the 20L from petco tanks with a $2.50 50 pound bag of of play sand. Here is a picture of my first ever hardscape. I have lots to learn so i would really appreciate a critique. This will always be my sand box and it will not see plants, fish or water for that matter. again your critique is more than welcome. once i get the delivery of my 120-H i will start taking pictures with a better Camera, I promise.
