Strengthen Acropora Against Acro-Eating Flatworms
- Helps Reduce Acropora-Eating Flatworms (AEFW)
- Supports Coral Tissue Strength, Recovery & Basal Growth
- Pairs Well with KZ Coral Booster
Korallen-Zucht Flatworm Stop is a specialized coral supplement designed to help Acropora withstand and recover from Acropora-Eating Flatworms (AEFW). Rather than acting as a conventional flatworm medication, Flatworm Stop works by strengthening the coral while helping make Acropora less favorable to these tissue-eating pests.
KZ also recommends Flatworm Stop for stressed or ailing SPS corals. During KZ's testing, affected corals showed renewed basal growth and improvements in coloration, making Flatworm Stop useful not only when managing AEFW but also as a supplemental tool for supporting coral recovery.
When Should You Use Flatworm Stop?
Flatworm Stop is best suited for Acropora and SPS-dominated reef aquariums where AEFW are present, suspected, or a recurring concern. Because it works by supporting the coral rather than functioning as a quick-acting flatworm treatment, consistent daily dosing is important when using it as part of an AEFW management strategy.
It may also be useful for stressed SPS corals that need additional support for tissue recovery, basal growth, and coloration.
Flatworm Stop is not a substitute for good pest-management practices. When dealing with an active AEFW infestation, coral inspection, manual removal, dipping, quarantine, and other appropriate control methods may still be necessary.
How It Fits Into the KZ System
Flatworm Stop can be used as a standalone supplement or alongside KZ's ZEOvit system. It is considered a problem-solving product rather than one of the foundational components of the ZEOvit nutrient management system.
Flatworm Stop is commonly paired with Coral Booster as this combination supports coral strength, growth, coloration, and recovery while managing Acropora-Eating Flatworms.
Recommended Dosage
Dose 1 mL per 25 gallons of aquarium water daily.

Product Questions
You will not need to adjust the media, UV or skimmer. These will be absorbed by the acros and make them repel the flat worms. Regular water changes can continue as scheduled.
This will work by targeting the acropora and treating them to resist the flatworms and starve the flatworms. Rather than trying to treat the flatworms directly. Feel free to let us know if you have any further questions!
We have found flat worm stop to work really well on our systems in house. As to the method of eliminating the flat worms unfortunately the information provided from KZ is not as detailed as desired. From our understanding the flat worm stop will have an impact on the corals directly which can lead to the flatworms starving. Feel free to let us know if you have any further questions!
This is designed only for use against flatworms and no further information has been given about other parasites being effected. The manufacturer only lists as a treatment for flatworm. Feel free to let us know if you have any further questions!
Great question, as far as we are aware we have yet to find a case where flatworm stop has effected fish. If you have a specific concern we highly recommend giving the manufacturer a call.
