A pond is a beautiful addition to your garden. Whether you want a koi pond or an aquatic garden with lilies, there is a pond for every mood. Many instructional sites online will help you build a pond from scratch and there are also many prefabricated ponds for sale at gardening stores. One of the most important factors needed for a pond is often overlooked, however. A pond needs a good pump and good filtration in order to remain beautiful and healthy all year long.
When you start to shop around for garden pond pumps, you need to know how many gallons your pond is. If you have no idea, there is a simple formula you can use. While measuring in feet, multiply the length times the width times the depth and multiply this total by 7.48. For example, a pond that is 10 feet long, 5 feet wide and 2 feet deep would be 10 x 5 x 2 x 7.48 = 748 gallons. It is important to know how many gallons your pond is because the pond pumps are rated by how many gallons per hour (or GPH) they pump. You want to pump at least half your pond total once an hour though ideally, you want it closer to the entire volume. A 1000 gallon pond should have a pump rated at 1000 GPH. Small ponds (1000 gallons or less) work well with submersible pumps, but if you have a large pond, you may want to look into external pumps.
Another important factor to consider are the different types of garden pond filters that are available. Mechanical filtration removes debris like leaves by passing water through a skimmer or large pore open cell foam. Chemical filtration uses materials like carbon to trap particles and remove chemical contaminants. Biological filtration is the most important. It uses the nitrogen cycle to break down and detoxify organic waste.
If you are not familiar with the nitrogen cycle, it would be wise to study it. Basically, it creates colonies of beneficial bacteria in your pond to keep the water healthy. There are many models available that combine these features and different filtration types. For example, some pond filters have two chambers. One chamber has a sponge which traps debris (mechanical) and beneficial bacteria (biological) grow here. The empty chamber is used for chemical filtration when needed. Pond filters are either submersible or external. Submersibles work better on smaller ponds while external filters are required for large ponds.
When choosing a pump or filter remember, these operate 365 days a year. Cheap models may end up costing more if they fail. Look for warranties that last longer than one year. If you are shopping for external options, ask how loud they are. Remember, your pond is supposed to invite serenity and reflection, not maintenance issues.
Having a garden pond in your own backyard is a great luxury, but in order to really be able to enjoy it, you must make sure that the pond operates properly and stays clean. By knowing some of the basics of garden pond filters and garden pond pumps, you are well on your way to making sure you have just what you need to keep your garden pond functioning at optimal levels.
Just think of how nice it will be to be sitting out on your patio or gazing out the window of your quaint workspace from a garden building tucked away in the corner of your yard, taking in the tranquil atmosphere in and around your garden pond, complete with all the sights and sounds that come with it. If you have a properly functioning and clean pond, you can enjoy that tranquility for a long time to come.
