The beauty of a pond is something everyone can appreciate. A flash of golden fish swimming in clean, clear water beneath the pads of waterlilies is a sight to behold and enjoy. Add the sound of a running waterfall and you have a dream come true in your backyard.
Keeping pond water clean and clear is the basis for a healthy pond that requires little to no maintenance. Fortunately, it’s relatively easy to create a proper pond environment that benefits your fish and plants. Follow our not-so-secret steps to ensure a naturally-balanced, low maintenance pond throughout the year!
Circulation: Make sure your pond pump is the correct size for your pond and waterfall. A pump provides valuable aeration to the water. Several variables need to be considered when choosing a pump, such as the size of your pond and the height of your waterfall. Aquascape makes it easy to select the right size pump with our brand new Pond Pump Selection Guide.
Filtration: More often than not, when answering questions about pond water quality, we find that people don’t have proper filtration installed on their pond. If you had your pond built by a Certified Aquascape Contractor, you should have no worries. But for others, you want to make sure your pond has both a biological filter and a mechanical skimmer. The biological filter is the start of your waterfall and adds beneficial bacteria to your pond. The mechanical skimmer is similar to a pool skimmer, removing surface debris such as leaves and sticks. Ideally, you want to position the biological filter and skimmer at opposite ends of the pond. This ensures movement throughout the entire pond so you don’t end up with stagnant areas.
Rocks and Gravel: Ponds can be made various ways. Some are created with concrete, others with a simple pond liner. We believe in an ecosystem approach to the pondering lifestyle and use rocks and gravels in our ponds, after installing underlayment and liner. Gravel provides much-needed surface area for beneficial bacteria to grow. Your fish will graze on these bacteria, as well. The gravel won’t be a breeding ground for muck and debris if you ensure that your low maintenance pond has the proper pump and filtration. The ecosystem works together so it’s important not to eliminate any of the elements.
Fish: While fish keeping is fun, your finned friends play an important part in the overall ecosystem of your pond. They eat algae and their waste becomes fertilizer for your pond plants. Too many fish, however, can pose a problem. A good rule of thumb is to limit your fish load to no more than 10” of fish per 100 gallons of water. So if you have a 20 fish at various lengths totaling 300” when combined, then you need a 3,000 gallon pond.
Plants: Plants play a critical role in the pond’s ecosystem due to their filtering capabilities. Plants absorb nutrients from fish waste and help starve algae of its food. During hot summer months, make sure to have at least 40% of your pond’s surface covered with plants. You can accomplish this with waterlilies and various marginals like mosaic plant, or floating plants like water lettuce and water hyacinth.
And now you know the secret to a truly low maintenance pond. Start with the basics and create a naturally balanced pond with a combination of proper circulation, filtration, fish, plants, and rock and gravel. You’ll be amazed at how easy pond-keeping can be!
