FLATWORM EXIT ITSELF IS QUITE SAFE TO FISH AND INVERTEBRATES.
However, the body fluids of flatworms can be toxic to some reef inhabitants when present in a too high concentration. This body fluid is sometimes excreted when flatworms die.
SO WHEN YOU USE THIS PRODUCT IT IS IMPORTANT TO DO THE FOLLOWING FIRST:
Siphon out as many flatworms as possible.
Keep sufficient fresh activated carbon in a canister ready.
Turn off UV, ozone and remove activated carbon. Keep the skimmer turned on.
