在家养什么宠物？鱼缸水质变黄别忘了除藻换水这招，改善环境，让你的小伙伴们享受清新的天地！要让鱼儿健康生长，一定要定期清除鱼缸中过多的藻类或是控制藻类的生长，因为若鱼缸藻类过多，会使水质混浊造成二氧化碳上升，使鱼只缺少氧气而死亡。对于不同藻类的清理，也要用不同的方法，比如定期换新水、稳定水中酸硷值等。

一、fish tank出现algae reasons

Nutrient overload

When the nutrient levels, nitrogen, phosphorus and organic carbon are too high and exceed the self-purification capacity of the water body and filtration system, it creates an ideal environment for algae growth.

Adequate lighting

Especially in well-lit conditions, algae organisms will grow more vigorously and frequently. The most common types of algae in fish tanks include green water, membrane algae, filamentous algae, mosses, black beard algae and silica algae.

Excessive nitrate levels

Green water mainly caused by excessive accumulation of nitrates and phosphates in the water leads to rapid growth of algal populations.

Frequent changes in water temperature or pH value

二、Control Algae Growth Methods

Remove dead algae cells

Algae can rapidly multiply in aquatic environments; they consume dissolved carbon dioxide from the water which causes a rapid increase in pH values; large amounts of dead algal cells consume oxygen from the aquarium environment which disrupts its quality affecting aquatic life's growth.

Maintain stable acidity-alkalinity values

If there is a significant amount of algae present among aquarists can adjust hardness level/temperature/pH etc., to suppress algal growth.

Use appropriate algicides

In order to effectively control proliferation when sufficient chlorine is available within waters (such as during regular maintenance), one may use specialized chemical agents that inhibit their multiplication such as copper sulfate crystals dissolving into solution after waiting until liquid turns blue these professional treatments provide excellent results.

Regularly clean your fish tank

5、Maintain cleanliness on a daily basis

三、Different Algae Cleaning Methods

1.Green Slime - Mainly grows on glass surfaces or stones inside aquariums with green film-like layers formed by this type of slime using small shrimp like Amano shrimp Black Line Corydoras White Pearl Corydoras you can clear out this type 2.Black Hair Algae - Most commonly found growing amongst plant leaves When you notice such prolification within your home aquarium immediately remove them using scissors otherwise rely upon specialized cleaning solutions 3.Membrane Algae - Grows on plants' leaves rocks walls & substrata Handling requires either manually removing strands through hand-held tools or introducing herbivorous species known as "algae-eaters" who naturally devour this nuisance 4.Filamentous Algae - Found mostly growing around vegetation stems & gravel In case you spot heavy infestation consider trimming away long filaments completely before attempting other methods
