Remove Green Algae - Checklist
Green algae are not threatening, but they can become a nuisance and affect the water quality. It is easy to remove them by hand.
Removing green algae from aquariums
It is not uncommon for green algae, such as filamentous algae and floating algae, to be found in aquariums. Although not considered threatening, they should not be underestimated. Especially not when they proliferate. Because this can be an indication that the biological balance in the aquarium or garden pond is no longer intact.
- If filamentous algae rarely occur, they need not be removed.
- If necessary, these species of green algae are simply fished manually out of the water.
- The occurrence of filamentous algae is one of the reasons for checking the quality of the aquatic fish.
- Excessive phosphate and nitrate levels promote the spread of green algae and are therefore a warning sign.
- Reconsider water care in this context
- Inadequate water changes and excessive feeding could be the cause.
- Poor planting may also be responsible for increasing the prevalence of green algae.
- If necessary, add CO2.
- Do not place aquarium too well - even direct Sunlight favors algae formation.
- Lighting periods should not be too short, but not too long.
- Put shrimp into the pelvis, they like to eat algae and thus support the biological balance.
- Many snails and fish are algae-eating aquarium animals.
- Avoid algae-based chemicals.
Increased algae formation prevent in the garden pond
Algae also occur in garden ponds. At normal nutrient concentrations, they live in harmony with other aquatic animals and plants, so there is no cause for concern. The situation is different, however, if the phosphorus content in the water increases, because this favors the living conditions of the algae. Fish feces, heavy rains, lawn fertilizers and foliage are possible causes.
- So that the pond water remains clear, turn off all phosphorus sources.
- Use as nutrient-poor sand as ponds.
- Low-phosphate groundwater is best suited as pond water.
- Floating blades automatically remove algae and excess nutrients from the pond.
- Floating skimmers automatically drain the surface.
- A good filtration system reliably removes algae and excess nutrients from the pond.
- The shell flower is a floating pond plant that naturally restricts algae growth.
It is best to regularly fish algae by hand from the garden pond or aquarium. However, with increased algal growth, the water should be analyzed to get to the root of the problem. With the appropriate countermeasures you get the water quality quickly back under control. It is best to pay close attention to the preservation of the biological balance.
