I have found another tank, a 55 gal.

This one will have a false bottom, waterfall, stream and for the background, no more GS and silicone, I will be using "kitty litter" clay. I want a lot of broms and air plants. I like the fact that I can stick them directly into the clay. I am using Quickcrete for the waterfall and stream, haven't decided if I am going to paint them or not, it looks pretty good the way it is, but it is only the first coat. I have a few pics of the false bottom, stream and waterfall. I am not going to rush this one, I have a pic in my mind of what I want, I hope I can come close to that!
I will take more pics when I can start on the build again..waiting for the cement to cure will seem a lifetime...LOL
I have two spaces for pumps...stream on the left and waterfall on the right. I had to make the FB a little offset for the waterfall, it will be sitting in the corner.
Sorry for the crappy photo, the sun was shining in. The FB with mesh, it took quite a while to get it right with all the angels.
I used the styrofoam used by florists, easy to carve. After several hours of carving and adding "rocks" they are ready to cement.
This is after 2 coats of Quickrete. It took quite awhile to get the thinned cement to cover this type of foam, the second coat was much quicker.
