After a disease treatment, the remainders that are now not required anymore should be removed as quickly and as entirely as possible. This avoids unnecessary water pollution and thus the forming of a new stress factor.

The highly active special active carbon sera pond super carbon removes not only treatment remainders but also other dangerous toxic substances, which for instance can be washed in unnoticedly by rainfalls (environmental pollutants, fertilizer components, herbicides, pesticides, among others) quickly, effectively, without side effects and without affecting the pH.

2 kg (4.4 lb) sera pond super carbon remain active for 6 weeks in up to 4,000 liters (1,057 US gal.) of pond water.
