Humic substances are not necessary for betta fish, but they can provide some benefits. Humic substances can help create a more natural environment for bettas by mimicking their natural habitat and providing a source of beneficial bacteria. They can also help to lower the pH of the water, which may be beneficial for bettas that prefer slightly acidic water. However, it's important to use humic substances in moderation and to monitor water parameters to ensure they do not negatively impact the overall water quality. **

Humic substances or similar substances can be introduced into the aquarium in several ways. One common method is to use commercially available products such as peat moss, which can be placed in a filter bag or directly into the aquarium to release humic substances over time. Another method is to use natural materials such as driftwood or leaves, which release humic substances as they break down in the water. Additionally, there are liquid additives specifically designed to introduce humic substances into the aquarium. It's important to monitor water parameters and the behavior of the aquarium inhabitants when introducing these substances to ensure they are not adversely affecting the ecosystem. **
