Pond Planning and Care FAQ
From care to construction
How to build a pond is usually the first question people ask when thinking about creating their own backyard retreat, but there is truly so much more to consider such as maintenance and care. Not only will we help explain some very important steps of how to build your pond, but we will also show you how to keep it healthy and you and your wildlife happy! Read through our questions and answers below to help you in your journey to creating and keeping your own backyard pond or water garden.
What is the perfect spot to build my pond? Your pond should not be in an area that is exposed to direct sunshine all day long (this promotes excessive algae growth). We suggest building your pond in an area that has a lot of foliage that provides shade. If not, it is highly recommended to add plants. Try and avoid leaves if you can. If you plan on adding fish to your pond, the water depth should be at least 6 ft. Your embankment should be about 30 degrees, have a terrace form, and provide stand areas for plant baskets.
Which pump is suitable for which pond? Picking the right pump depends on a lot of pond factors.
The pond size is not the decisive factor for selecting the right pump. Instead, you should ask, what should the pump be used for?
How is the pond calculated for size? You can start by finding the volume of your pond with the formula, L x W x H (length times width times height). Depending on the number of flat water zones subtract approximately a third to half. This should help you
How high should a fountain be? In general, a fountain should not be higher than the radius of the pond.
From which point is the height differential calculated for a watercourse? The height differential for a watercourse is measured from the water level to the upper source point.
How much water evaporates daily in a pond? Evaporation varies per pond. It depends on a number of factors like the location of the pond , the strength of the sun, effects of the wind and what kind of accents you have (if any).
Preparing for the Winter
How will the winter affect my pumps and filtration systems? Pumps and other equipment that are sensitive to freezing must be switched off, removed, and stored in a frost-free location. In smaller bodies of water, it is important that the warmer survival zones for the fish are not recirculated. In larger bodies of water, a small water exchange in the bank area helps prevent freezing over. The pump should be carefully cleaned and stored in a water-filled container in a frost-free location.
Can my pond freeze over? Yes, your pond can freeze over. We highly suggest using an aerator or the OASE IceFree to prevent your water from freezing completely. It allows for gas exchange in a small area of the pond by keeping a small area unfrozen.
Should the goldfish spend the winter in the pond or should you bring them inside? If the pond is less than 3 feet deep, then we recommend that the goldfish spend the winter in a container that is as large as possible. In this regard, the water temperature should be between 39°F - 46°F (4°C - 8°C).
Do you recommend breaking the ice for purposes of aeration? No! The fish could be injured by the sound waves which can result in "stress" that will increase the oxygen consumption of the fish.
How do I get my underwater plants through the winter safely? Most floating plants should be skimmed so that they do not introduce any biomass into the pond. The stems of bank plants and marsh plants should only be trimmed in spring. In winter, they have a type of chimney function that ensures fermentation gases escape.
When should I start my pond filter after winter? Biology plays an important role in a pond filtration system. Because the significant microorganisms only start to work at around 50 °F, we recommend starting up the filter when this temperature is reached.
