How good is sea cucumber pond green algae?

First of all, the range of green algae is relatively large. Chlorella include single-celled algae that grow in suspension, as well as multicellular algae such as filamentous algae and cotton wool that grow sessile. I don't know what kind of green algae the problem refers to.

Chlorella is a very common algae in the process of fish farming, if it is not handled properly, it is very harmful to fish, if it is only for koi, its harm is mainly manifested in:

Outdoor large water surface aquaculture: the large water surface referred to here is a mud pond or a large non-filtered cement pond, for this kind of water body if the water quality is too fertile or usually change the water, feeding is not appropriate, the green algae in the water body is easy to multiply quickly, once the overpropagation is spreading, it is easy to cause blooms, this situation is very harmful if not properly treated. This situation indicates that the water body has seriously deteriorated, and the oxygen in the water body will be seriously insufficient, and the fish are very prone to hypoxia, and the other possibility is that the fish are easy to cause fish poisoning and death after eating these dead algae; From this point of view, as long as the green algae does not overload (affecting the water quality), there is almost no harm to the koi, but when it is overpropagated, it is still very harmful to the koi.

Indoor fish tank or filter pond culture: In this case, the appearance of green algae will affect the green of the water body, which will affect our usual appreciation of koi, if this water body is long, it may cause the filtration system to stink and cause the water quality to deteriorate, which will affect the health of koi. The above is just talking about the harm of green algae to koi, if there is an excess of green algae in the water body, what to do with it, the advice for stepping on the fire is:

For mud ponds, you can use spores or change the bottom to transfer water, in addition to paying attention to the timely change of water and reasonable feeding, these are good ways to prevent green algae, if a large number of blooms have appeared and formed a bloom, we must first find a way to discharge these dead algae out of the fish pond, in order to reduce its harm to koi, if it is a fish tank or filter pond culture, when the water quality begins to turn green, we must see if there is a problem with filtration, and pay attention to the sewage, in the high temperature season when the algae grow vigorously can turn on the UV lamp.

Not good, because too much green algae makes the nutrient of the sea pond and pond scarce, winding the sea cucumber, affecting the growth, a large number of green algae, easy to rot, polluting the water quality, deteriorating the water body, resulting in the reduction of oxygen content at the bottom of the water, and even hypoxia, which brings difficulty to the growth and disease prevention of sea cucumber.

A lot of green algae is very beneficial. Because this can provide a lot of oxygen to the sea cucumber pool, it can make the survival rate of sea cucumber higher.

The green algae in the sea cucumber pond can be used as bait for sea cucumbers**. Because it is rich in a variety of trace elements and a variety of amino acids, sea cucumber can feed on humus after the death of green algae, so as to supplement the bait and promote the growth of sea cucumber.

Chlorella can also absorb and utilize nutrients such as nitrogen, phosphorus, and silicon. When the concentration of nutrients in the sea cucumber pond is too high, the green algae can quickly absorb nutrients as a reserve. When the nutrients in the sea cucumber field are insufficient, the green algae can also release nutrients for the sea cucumber to use.
