What equipment do you need to raise fish in straw vat? Can aquatic plants rot without carbon dioxide? Do we have to use lights? How did the fish tank turn green on the third day after changing water?

You can't raise fish in a straw basin. Herbivorous fish should raise some algae-eating fish or creatures.

1. Need adequate lighting. If you have money, it is recommended to use a professional water lamp. Be careful not to be in direct sunlight, there will be bad things such as algae bloom.

2. Bottom sand or sediment, if fish are raised, should not exceed 5 cm, and grass should not be less than 4 cm.

3. It is not recommended to use chemical fertilizer, which affects fish and other organisms. A small amount of base fertilizer can be added under bottom sand or sediment (large amount is toxic to organisms).

4. The water depth is less than 30cm, which will affect the lighting.

5. Thermometer is indispensable. Good for grass and fish. A few dollars cheaper.

6. To raise red grass with carbon dioxide, a small number of rare varieties are needed. A large number of them are highly toxic to living things. It's up to you. Generally, green grass tanks are not used.

Lights are necessary.

Outbreak algae

Algae bloom is caused by excessive light or natural light. Reduce the illumination intensity to 0.5W per liter of water and the illumination time to 5-6 hours. It is best to turn on the lights for 3-4 hours in the morning and afternoon respectively. If the natural light is too strong, pay attention to shading! This process takes about half a month.

Adding algae-removing organisms such as black shell shrimp.

Green water is an algae bloom. Suggestion: 1. Add a piece of medical absorbent cotton to the filter tank, let the water filter from it, and then wash it after it is dirty (never use detergent or the like). Reduce the light to 6 hours. In addition: 3. (Snails eat grass, but straw pots can't be used.) Some netizens have done experiments. Snails (not snails) have strong ability to filter green water 10 * 66. You don't need it. You can still eat it. 4. The filter barrel with sterilization ultraviolet lamp can also solve this problem.
