The nemesis of the pond world. Pond algae is one of the so called red flags of backyard pond ownership. This article will help the pond keeper control and manage this pond scum dirty word.
What causes pond algae?
Algae in ponds is caused by several contributing factors. Excessive nutrients caused by fish waste or uneaten goldfish and koi fish food, amount and duration of direct sunlight and/or a lack of pond filters. While all of these factors contribute to the amount of algae in the fish pond, they can all be controlled to allow the health of your pond to flourish in the years ahead.
Excessive Nutrients in the Pond
The amount of fish that live in your pond or fish load directly relates to how much algae growth you have in your koi pond. The more fish you have, the greater the chance that you will have more pond algae that needs to be controlled.
The amount and duration of sunlight that your pond receives directly effects the amount of algae growth that your fish pond will have. Algae in ponds is a plant, and it loves sunlight. Less sunlight equals less algae in most cases if everything else in the pond is well balanced. Pond plants can be added to the water feature in order to help combat natural algae growth.
Pond filters installed on the backyard fish pond and waterfalls can tremendously improve the water quality of the ecosystem within your water feature. There are several pond filters that can be installed that can aid in a properly balanced pond.
