過硫酸氫鉀復合鹽到底是什么？
What is potassium bisulfate complex salt?
1、根據養殖品種池塘底部情況，根據池底情況，選擇不同含量和配方產品。改底有改底的配方，凈水有凈水的產品。
1. Select products with different contents and formulas according to the bottom of the pond and the bottom of the pond. There is a formula for changing the bottom, and there are water purification products for water purification.
2、使用用量要減半，堅持少用多次。多數養殖池塘，往往前期因大量使用氯制劑、表面活性劑產品，使得池塘底部板結，下面積存了大量有毒有害的東西，此時用量不能大。
2. The dosage for the first time should be halved, and it should be used less and more times. In most aquaculture ponds, the bottom of the pond is hardened due to the large use of chlorine preparations and surfactant products in the early stage, and a large number of toxic and harmful things are stored in the lower area. At this time, the dosage should not be large.
3、一次使用，注意水體溶氧，建議增氧。打破板結后如果底部溶解氧不充足，會造成積存的亞硫酸鹽、硫化氫等毒物發散到水體，造成應激。
3. For one-time use, pay attention to dissolved oxygen in water, and it is recommended to increase oxygen. After breaking the hardening, if the dissolved oxygen at the bottom is insufficient, it will cause the accumulated sulfite, hydrogen sulfide and other poisons to spread to the water body and cause stress.
4、堅持周期性改底，不要等到問題出現了再去改底，夏季高溫期間細菌生長繁殖快，改底周期縮短到4-5天一次。
4. Adhere to the periodic bottom improvement. Don't wait until the problem occurs. During the high temperature in summer, bacteria grow and reproduce quickly, and the bottom improvement cycle is shortened to once every 4-5 days.
5、使用時堅持“過硫酸氫鉀復合鹽+有益微生物”模式，注重水體微生態平衡。發揮有益菌，藻類的綜合生態效應看，使水體達到微生態平衡。
5. Adhere to the mode of "potassium bisulfate compound salt + beneficial microorganisms" and pay attention to the micro ecological balance of water body. Give play to the comprehensive ecological effects of beneficial bacteria and algae, and make the water body reach micro ecological balance.
6、避免和堿性藥品同時或先后使用。輪番使用不同產品改底的時候需要注意前后產品的搭配禁忌，切忌跟風使用產品。使用過氯制劑，隔2天再用。
6. Avoid using with alkaline drugs at the same time or successively. When using different products in turn to change the bottom, we should pay attention to the matching taboos of the products before and after, and avoid following the trend. Use perchloride preparation and reuse it every 2 days.
