Fish Load: When calculating your fish load, think of it in pounds of fish or total inches. For example, one 6” fish can weigh as much as four 4” fish. The number of fish will affect the overall fish load. Although 10 small fish may only produce the waste of one large fish. With this said, remember that your fish are growing and in many cases multiplying. Always plan for the future and be careful not to overstock your pond.

Proper Filtration: The size and type of your filtration system will depend on your total fish load. If your filter is not properly sized for maximum potential, your fish will outgrow the filter. In most cases filters on the market are rated for ponds containing no fish or a minimal fish load. It is always best to get a filter that is rated for at least 2x the water volume of your pond.

Aquatic Plants: A rule of thumb is to have 60% plant coverage. This should consist of submerged, floating and marginal plants. Floating plants pull their nutrients directly from the water. Rooted plants and marginal plants, create a great place for your fish to hide from predators. Please note when aquatic plants are not present, algae will take their place.
