For instance, it is usually a good idea to rinse the pond out before installing it into the ground incase there are any chemicals left over from the manufacturing process.
The first thing to do is have a look at the instructions included with the pond to read any startup procedures that might be required. To learn more please see the image on the right or the box-welded polypropylene liners in our store. A box-welded liner is made by heat welding flat liner panels into a 3D 'box'. If you still want the convenience of a preformed shape and no folds in the liner, then maybe a box-welded liner is right for you. On the flip side, if you plan on adding a large waterfall and lots of fish that will require pumps and filters, you may want to consider building a more advanced pond out of a flexible pond liner to get a little extra depth, size and flexibility with regards to design. For more information on pond plants, please see our page on pond plants. In fact, if going with this approach, instead of adding a pump and filter to keep your water clean, you would probably be fine just adding some floating oxygenating plants and other plant life to filter the water naturally. If your main goal is just to create a small pond in your backyard to plant some water lilies, or to add a small focal point to your garden without a lot of expense or work, then a preformed plastic pond will likely work fine. Keeping the above in mind, preformed liners aren't all bad. We have heard reports that some brands are prone to cracking.There's not as much room for things like waterfalls, plants and aquarium fish without overcrowding.It's usually not possible to keep traditional pond goldfish and koi due to the shallow depth and small size.Shallow water is more prone to overheating which creates problems for fish and promotes pesky algae growth.It's more difficult to create a proper ecological balance in a small pond, which can lead to poor water quality.The smaller size can have repercussions later including: The main disadvantage is that preformed ponds are usually quite small and shallow compared to custom-built liner ponds. You may find it’s easier simply to build one from a combination of liner, black expanding foam, and the rocks you have to purchase or collect anyway.There are however some disadvantages to preformed plastic ponds over traditional liners, or other types of preformed options. Either way, you’ll need lots of extra rocks or other materials to disguise the supports and edges of the waterfall feature.
It’s also easier to build a wood or concrete support for the preformed waterfall structure when it’s not attached to an existing pond form. This allows you to create a custom lined pond of any size and shape with the waterfall in any position or placement. On the flip side, if you plan on adding a large waterfall and lots of fish. Make sure you have extra dirt, concrete blocks, rocks, or other materials to support the raised side sections that form the waterfall feature since the rigid liner has a fixed position.įor an easier installation, ordering a preformed plastic waterfall feature that isn’t attached to the edge of a pond form. Preformed plastic ponds are often a popular choice among new pond builders.

However, it is faster to install a preformed liner when you’re trying to add a waterfall without any extra work. Preformed ponds take more work during excavation than those lined with flexible materials because the soil must be perfectly graded and shaped to support the rigid liner. Waterfall preformed ponds are the quickest way to get a splashing water feature in your backyard.
