Flatworm eXit is safe to fish and invertebrates. However, dying flatworms can be toxic to your reef when present in high concentration.

When you use this product, do the following:

  • Siphon out as many flatworms as possible.
  • Keep fresh activated carbon in a canister ready.
  • Turn off UV, ozone and remove activated carbon. Keep the skimmer turned on.

Many people have treated their reef tank(s) successfully using Flatworm eXit without any problems. The most important factors are reducing the number of flatworms before starting the treatment and reducing the amount of the flatworm toxin, released when they die, as fast as possible.

Do not underestimate the number of flatworms in your system, a significant number of flatworms can be hiding in crevices. Try to flush out any flatworms out of there with a powerhead or a turkey baster. Siphon out those flatworms as well.

Do not underestimate the amount of toxins these flatworms can excrete.

Further significant reduction is accomplished by siphoning out as many dead flatworms as you can.

Any toxins released by the dead flatworms in the water has to be reduced further by using about 1 pound of fresh high quality carbon for every 50 gallons. The carbon has to be used in a canister with a sufficient forced water flow.

Take sufficient time for treating the tank and monitor your tank for at least 6 hours after the treatment.

It is also wise to have at least 25% water ready for a water change.


Read all the above text before commencing with the treatment!

1 drop for every 4 liters or 1 gallon
The dropper contains approx. 300 drops (10ml). The dropper cap holds approx. 90 drops. So 1 cap full is good for 360 liters or 90 gallons.

Add it in a high flow area of the tank.
It should start to work within 30 minutes.
If within 45 minutes no visible death of flatworms occurs add 50% more.
As soon as the flatworms start to die, commence with the activated carbon to take out any toxins. See the above.
After an hour or so you can turn any UV or ozone on again.
Keep out of the reach of children! Only for aquarium hobby use.
