Here are professional recommendations on the use of aquarium salt for betta fish:
I. Specifications for Daily Salt Use in Feeding
Concentration Control
- Preventive use: Water salinity should not exceed 0.1% (1 gram of salt per liter of water).
- Therapeutic salt bath: Short-term soaking at 3-5% concentration, no more than 20 minutes each time.
- Long-term conditioning: Maintain 1% salinity and replenish salt regularly.
Salt Selection
- Use iodine-free sea salt or aquarium-specific salt.
- If using table salt, boil it to remove iodine before use.
II. Applications in Disease Treatment
Applicable Diseases
- Water mold disease: Use in conjunction with methylene blue (10mg/L solution + 0.5% salt).
- White spot disease: Raise water temperature to 30°C + 3% salt bath.
- Tail rot disease: 2-3mg/L medication + 0.5% salt as an adjuvant.
Operation Key Points
- Change 1/4 of the water daily and replenish salt during treatment.
- Terminate the salt bath immediately if abnormal behaviors (such as body tilting) occur.
III. Precautions for Breeding Period
- The breeding tank should maintain a salt-free environment (pH 6.5-7.2, soft water is preferable).
- Salt can affect the development of fish eggs and the survival rate of fry.
IV. Collaborative Water Quality Management
During salt baths, monitor:
• pH 6.5-7.0
• Ammonia nitrogen < 0.2mg/L
• Nitrite < 0.05mg/L
V. Alternative Solutions
Good water quality management (temperature 24-28°C, regular water changes) can completely replace preventive salt use.
