Water parameters

  1. Keep ammonia and nitrite at 0 ppm before adding livestock.
  2. Maintain stable temperature and pH instead of chasing exact numbers.
  3. Perform regular water changes based on stocking level.

Feeding

  1. Feed a varied, species-appropriate diet and remove uneaten food promptly.
  2. Avoid overfeeding during the first day after arrival.

Compatibility

Review the product facts and current tank setup before introducing new livestock.
