After watching what feels like every video on youtube, I decided to try and make my own decorations. I decided on the tried and true styrofoam/cement method, and also decided on doing a sandfall. I have made a huge mess and did a lot of second guessing the look, but as of now, I like where it is sitting.
I have used about 2/3rds of a 4x8 sheet of 3/4" stryofoam, 2 tubes of 100% silicone, and maybe 1/8th of my 10lb bag of quickrete mortar mix. There is only one coat on it now, but it will get more. I carved out a couple small areas on the top flat rock to maybe add some small fake plants.
- There are two tunnel entrances for the fish at the front. Its pretty much a big "U" that goes through the structure.
- The taller rock structure conceals the 1" pvc
pipe that will transport the sand, drop it, and hopefully all the sand falls into the "bowl" in the center, which will recycle the sand.
