Product efficacy 产品功效

Water purification: degrade ammonia nitrogen, nitrite nitrogen, hydrogen sulfide, methane and other harmful substances, reduce sedimentation, purify water quality.净水:降解氨氮、亚硝酸盐氮、硫化氢、甲烷等有害物质，减少沉淀，净化水质。
Oxygenation: flocculation of suspended solids in the water body, improve water transparency, favor the photosynthesis of phytoplankton, in order to increase the dissolved oxygen in the water body, to avoid floating head, to prevent flooding of the pool.氧合作用:絮凝水体中的悬浮物，提高水体透明度，有利于浮游植物的光合作用，以增加水体中的溶解氧，避免浮头，防止水池淹水。
Water nourishment: It is conducive to the propagation of plankton, provides nutritious natural bait for aquatic animals, creates suitable breeding water color and benign food chain, and ensures that the water quality is alive, tender and cool.水体营养:有利于浮游生物的繁殖，为水生动物提供营养丰富的天然饵料，创造适宜的养殖水色和良性食物链，保证水质鲜活、柔嫩、凉爽。

Scope of use

All kinds of marine and freshwater nursery pools and nursery pools.

Usage and dosage

Dissolve and dilute the product with water, then sprinkle evenly in the whole pool.

Improvement of water body: Use 500ml of this product for 1 meter of water depth per mu of water surface (double the dosage for the first time), and use it once every 10-15 days, and use it in additional quantity in high temperature season or when the water quality is deteriorating;

Nursery or cultivation of rotifers: before the seedlings enter into the pool, splash 10-20ml per cubic meter of water, after the seedlings enter into the pool, splash every 2-3 days, the dosage is 30-40ml per cubic meter of water. 50ml per cubic meter of water for the cultivation of rotifers.

Use as strain: Inoculate the product into the prepared culture medium according to the ratio of 1:10, and incubate anaerobically under light for 5-7 days, then it can be used as an expanded strain.

Precautions

1. Separate from antimicrobial agents, disinfectants and other chemical agents, need to be used at least 3 days apart.

2. It is normal phenomenon if there is precipitation, floating matter or a little gas production after the product is left to stand, it does not affect the use of the effect.
