Here are some pics of a pondless or disappearing waterfall I just started at a subdivision entrance center island. We placed 9 tons of moss boulders with the mini excavator yesterday. Today we will finish out a lot of the feature with foam, gravel and assorted sized river rock. This will have an Easy Pro EP 10,000 gph pump. I used a Savio waterfall well, and I also used Aquascape aquablox so I wouldn't have to dig as large a hole I will be landscaping the entire entrance in the next couple of weeks. This is the first time I have had control of the plantings surrounding one of my features so I am pretty excited. I will post more pics as I go along.
