FAQ
Can I use Flatworm EXit if I have sensitive reef inhabitants?
Yes, but care must be taken. The product is safe for fish and invertebrates, but the body juice from dead flatworms can be toxic to some reef species. Ensure all flatworms are removed and follow the recommended treatment steps to minimize risk.
How much Flatworm EXit do I need for a 200-gallon tank?
For a 200-gallon tank, use 50 drops (1 drop per gallon). The dropper contains 300 drops, so this is approximately 1/6 of the full dropper.
Is the product safe to use during normal aquarium operation?
No. UV, ozone, and activated carbon should be turned off during treatment. The skimmer should remain on. Do not use during active filtration or lighting cycles.

Used Flatworm EXit after a large flatworm infestation. Followed all steps: siphoned out as many as possible, turned off UV and ozone, and used the product as directed. No further flatworms appeared and the tank remained stable. The dropper is easy to use and the instructions are clear.
Lily Mathis –
The product worked well in a 300-gallon reef tank. I removed most flatworms manually first, then applied the treatment. The tank stayed healthy after use. I noticed no toxicity in my corals, which was a relief.

Great product for dealing with flatworms. The dosage is simple and the instructions are thorough. I used it in a 250-gallon tank and followed all the steps. No issues with fish or invertebrates after treatment.
