When it comes to aeration kits, finding the right fit is critical. Properly sized aeration units infuse oxygen into the pond, circulate water, and help create a balanced ecosystem. Your fish will be happier and healthier, and you will have less organic material in your pond that fuels algae growth. When selecting an aeration kit, here are a few things to consider:
Pond Size
Aeration kits must be capable of circulating the total volume of water in the pond. If you do not know your pond’s size offhand, you can figure it out by determining the length, width, and maximum depth. Once you have these measurements, plug them into our handy pond calculator or follow the formula below.
Multiply the length by width by maximum depth, then divide in half to calculate the cubic feet in your pond. Water gardens are typically measured in gallons, so multiply the cubic feet by 7.48 (the number of gallons in a cubic foot) to determine the volume in gallons.
If your water garden has multiple ponds or is irregularly shaped, calculate the gallons for smaller sections and add those values together to obtain your total pond size.
Pond Depth
Water garden aeration kits feature energy-efficient diaphragm compressors that can wear out prematurely if operated in depths greater than recommended. When selecting a system, make sure you know your pond’s maximum depth, and double-check before buying if there is any doubt.
Pond Shape
Waterfalls cascading into multi-level ponds or irregularly shaped water gardens can add beauty to your backyard landscape. However, these uneven shapes limit the circulation of oxygenated water. For ponds like this, aeration kits with multiple air stones or diffuser plates are best to ensure that your water is circulating correctly.
