Flatworm eXit is a treatment for flatworms that is safe for fish and invertebrates but can release toxic body juices from flatworms when they die. It requires siphoning out flatworms before treatment and using activated carbon to absorb toxins. Care must be taken to monitor the tank for at least 6 hours after the treatment, and water changes may be necessary. The dosage is 1 drop for every 4 liters or 1 gallon, with specific instructions on application and monitoring.
