If you choose to order a net for your pond, you can actually order one in custom dimensions to fit your pond perfectly. Or you can purchase one that is already pre-cut as there will be many sizes to choose from.
Posted by Scott Willbanks to Do I Need a Pond Skimmer?
If you want to maintain a healthy pond, then you will need to look at the selection of pond skimmers that are available and choose one that meets your needs. This product works by collecting dirt, leaves, waste products, and other debris from the water's surface before it has a chance to sink to the bottom of the pond. This will help keep your pond clean and looking great. If your pond has other features such as a waterfall or fountain, the skimmer should be placed on the opposite side of the pond so that the water can naturally flow toward the skimmer.
In addition to a pond skimmer, you should also look at the selection of pond covers or netting that you can purchase for your pond. The netting serves as a protective barrier for your pond and can be quite durable, but the net will still allow some sunlight to get to the water. This can be especially helpful if you live in an area that is prone to bad weather. If your pond is located in an area near lots of trees, a cover can also help because the falling leaves won't be able to get into your pond.
