Precautions when using Calcium Oxide CaO

[Abstract]:
If Calcium Oxide CaO is exposed to the air for a long time, it will absorb carbon dioxide and turn it into powdered calcium carbonate, which cannot achieve the effect of pond disinfection.

1. If Calcium Oxide CaO is exposed to the air for a long time, it will absorb carbon dioxide and turn it into powdered calcium carbonate, which cannot achieve the effect of pond disinfection. Therefore, it is better to buy and use quicklime immediately, and it is better to choose the one with lighter lumps and no impurities. If the remaining quicklime is not used up, seal it in a plastic bag.

2. Calcium Oxide CaO should be added to the slurry and sprinkled while it is still hot. Do not pour the residue into the pool to avoid death by accidental ingestion of pond fish, and do not throw the whole lime into the pool for water disinfection.

3. Calcium Oxide CaO should not be applied simultaneously with nitrogen fertilizer. Quicklime generates a large amount of OH- in contact with water, and high ammonia content can easily cause ammonia poisoning in fish. Similarly, when the ammonia nitrogen content in the pool water is higher than 1.2 mg/L, it is not appropriate to use quicklime. In addition, quicklime can be used every other week after ammonium nitrogen fertilizer is applied, and it is forbidden to mix it.
