Q ：How is the filtration effect of the Pond Multi - function Surface Filter? A ：The PondMaster Pro Pond Multi - function Surface Filter, with its built - in filter basket, oil and skimming, wave - making and aeration, sterilization and filtration, and water purification and bacterial cultivation, effectively removes impurities, oil films, and harmful microorganisms from the pond, significantly improving water quality. Users can achieve remarkable results in a short time by reasonably setting parameters based on pond conditions, with even better long - term effects.

Q ：How often does the built - in filter basket need to be cleaned? A ：The cleaning frequency of the built - in filter basket depends on factors such as pond size, fish population, feeding amount, and surrounding environment. It is generally recommended to check it 1 - 2 times per week and clean it promptly when a significant amount of debris accumulates. During seasons with abundant falling leaves or when the pond is heavily polluted, the cleaning frequency may need to be increased.

Q ：What benefits does the wave - making and aeration function offer to the pond? A ：The wave - making and aeration function not only boosts dissolved oxygen levels to prevent fish from surfacing or dying due to oxygen deficiency but also promotes exchange between upper and lower water layers for uniform temperature and oxygen distribution. Adequate oxygen favors beneficial bacteria in breaking down organic matter, accelerating water purification, and inhibiting anaerobic harmful bacteria, thereby enhancing the stability of the pond ecosystem and being highly beneficial for fish growth.
