I am designing my first formal type swimming pool waterfall. I would like to use 3 sheer descent type weirs, preferrably lighted. I was thinking of using a 2' or 3' for the center weir and a couple of 1' weirs for the side weirs. Do you have any manufacturers that you prefer that provide good value and easy installation. I have been to both Jandy and Zodiac's website. Also for the main construction I was thinking of using concrete block and then tiling the block with a possible combination of marble and other tile. Are any natural stones or marble better than others? I am just looking for tips or pitfalls to avoid. I may have more specific questions as I get closer in the design. There is an existing source of water because I will be demoing the old falls. Here is a pic from Zodiac's website of something similar to what I am thinking. Thanks. I am glad there are some pool builders on here now.
