With our readymade waterfalls and fountains, complete with their water outlet fittings already installed in the waterfall, all you need to do is push your tubing on one end and push the other end of the tubing onto your pump. These waterfalls have all been water tested and are ready to go. We suggest using a real rock of matching color to the waterfall, to disperse the water as it comes out of the water source, placing other real rocks and pebbles can also help channel or redirect the water flow over the waterfall as desired. Our lightweight products give you the ability to create what nature does naturally. Have a balanced landscape full of variety, rocks large and small. This is often very hard to achieve with real rocks due to their weight. By using large to small rocks in your garden, as with low to tall plants, this will help in creating the various dimensions in a garden that make it an inspiring experience.
