魚缸氨濃度為什麼不正常?(Why is the ammonia concentration in the fish tank abnormal?)

1.新設缸硝化菌不夠:無法完全分解水中有毒的氨及亞硝酸鹽成硝酸鹽

>>>對策:添加硝化菌液/粉(約1週培菌)或向店家或同好索取已培菌的底砂或生物性濾材(珊瑚石、生化球、陶瓷環等)(約1~2天培菌)

2.舊缸過濾設備底層濾材清洗不當:用未除氯的自來水清洗過濾設備的底層生物性濾材，將濾材中可分解氨的硝化菌洗光光

>>>對策:用缸水或已除氯的自來水清洗濾材

3.舊缸過濾設備底層濾材太髒:硝化菌以過濾設備的底層生物性濾材當棲所，若過髒將導致可分解氨的硝化菌死亡

>>>對策:定期用缸水或已除氯的自來水清洗濾材

4.魚缸有機物過多:魚缸中的水草腐爛死亡、未食用完的餌料及魚的排泄物是魚缸氨含量升高的原因，產生的氨超過缸中硝化菌可分解的量

>>>對策:定期修剪水草、避免過量餵飼

5.氨的分解效能被抑制:由於硝化菌適合存活於攝氏20-30度水溫及pH6.5-8.5之間，超出水溫及pH值範圍時，分解氨的硝化作用就會被抑制

>>>對策:透過升(降)溫及換水，盡量將水溫及pH值控制在硝化菌所需範圍內

1. Insufficient nitrifying bacteria in the new tank: unable to completely decompose the toxic ammonia and nitrite in the water into nitrate

Countermeasures: Add nitrifying bacteria liquid/powder(about 1 week to grow bacteria) or ask for the sand on the bottom of the fish tank or biological filter material (coral stone, biochemical ball, ceramic ring, etc.) that has cultivated nitrifying bacteria from the store or friends with the same hobby(about 1~2 days to grow bacteria)

2. Improper cleaning of the bottom filter material of the used tank filter equipment: clean the bottom biological filter material of the filter equipment with unchlorinated tap water, and wash away the nitrifying bacteria that can decompose ammonia in the filter material.

Countermeasure: Use tank water or dechlorinated tap water to clean the filter material

3. The bottom filter material of the used tank filter equipment is too dirty: nitrifying bacteria use the bottom biological filter material of the filter equipment as a habitat. If it is too dirty, it will cause the death of nitrifying bacteria that can decompose ammonia

Countermeasures: regularly clean the filter material with tank water or dechlorinated tap water

4. Too much organic matter in the fish tank: the aquatic plants in the fish tank rot and die, uneaten bait and fish excrement are the reasons for the increase in the ammonia content of the fish tank, and the ammonia produced exceeds the amount of nitrifying bacteria in the tank that can be decomposed.

Countermeasures: regularly trim aquatic plants and avoid overfeeding

5. Ammonia decomposition efficiency is inhibited: Since nitrifying bacteria are suitable for survival in a water temperature of 20-30 degrees Celsius and a pH of 6.5-8.5, when the water temperature and pH range are exceeded, the nitrification of decomposing ammonia will be inhibited

Countermeasures: Try to keep the water temperature and pH within the required range of nitrifying bacteria by increasing (decreasing) the temperature and changing the water.
