Lew, it is just a big learning curve of trial and error. The last water I did I used Hunter Green for the deepest part and when all was said and done and the water in I did not like it. I thought the Hinter Green was too blue. So I got the Moss Green to use in its place. Once I am happy with the way it looks I start adding the falls and then the water.
Thanks guys for the compliments and the suggestions of color and pics to help me with this project.........Paul
