Here is the redo, it now has a PF3000 filter an aqua 40 watt UV, 2 inch tubing, the 3 tier is powered by a 3900 Calpump that has crapped out 3 times but i only paid for one because of warranty from builder, even though i totally tore the whole thing apart and rebuilt it similar. It is now about 8 by 9 by almost 3 feet deep. the smaller falls is powered by a home depot 2000 GPH submersible pump. Also the whole thing is granit Mohave gold rock and they were really heavy after lifting about 5 tons by hand. Hope you like, I Love it. I took the redo pictures at night so i tried to make them as bright as I could, also I am in Vegas and have a very small yard so this is as big as I can go. But i have about 4 months and have to replace the pump again. Thsi time with my own dime = (. Have a great day
