Is too much algae bad for koi?
It is true that algae creates oxygen during the daytime as a by-product of photosynthesis; however, at night it consumes just as much—if not more—than it produces. Large algae blooms in koi ponds can cause a dangerous enough drop in oxygen that it can result in koi death.
Can koi fish survive on algae?
Ornamental fish such as Koi, Shubunkin, and Comets (goldfish) are beautiful hardy fish that do well with the change of season. Fish do not have to be fed provided you do not overstock your pond. They will live off of algae, insects and other miscellaneous food that the environment provides.
How much algae is too much koi pond?
A general rule of thumb in fisheries science is that any more than 20-30% coverage of aquatic vegetation can be detrimental to quality fish production. This is because too much cover for baitfish disrupts the normal feeding behavior of sight feeding gamefish such as largemouth bass.
How does too much algae affect fish?
Algal blooms can reduce the ability of fish and other aquatic life to find food and can cause entire populations to leave an area or even die.
Should my koi pond have algae?
Algae is a normal function of a koi pond. Though it can be unsightly at the surface, it is normal to have some algae on the sides of the pond or even on the bottom. This algae can actually benefit the pond by keeping nitrate and other nutrient levels in check. Algae can also become a snack for koi fish.

How do I keep my koi pond crystal clear?
Beneficial bacteria living in the biological filter and throughout the rocks and gravel in the pond are another key component to achieving crystal clear water and reducing pond maintenance. The bacteria, similar to aquatic plants consume excess nutrients, but are also capable of breaking down organic debris.
Should a fish pond have algae?
The Good: Algae is not harmful to your pond or water feature. Algae actually performs a necessary and important role, just like any other plant in your pond -that is to absorb nitrates, which is what’s left in the water after your pond’s beneficial bacteria are finished degrading fish and plant waste.
Does algae suffocate fish?
When an algal bloom “crash” occurs, the water will appear to have turned black or clear overnight. The sudden die-off of algae will lead to a rapid decline in dissolved oxygen as bacteria decompose the dead algae. This can lead to dangerously low levels of dissolved oxygen, which can result in fish kills.
Is green algae bad for fish?
Green algae are considered as “good” algae, but their growth should be kept under control so they won’t deprive the fishes of nutrients. Some aquarists let green algae thrive to serve as a dietary source for their fish.
