Product Questions

I have to break my tank down and move it. I was thinking to dip all the rock etc in flatworm exit before setting back up. Will this work or does it have to be in the tank? I understand that the eggs are not affected by chemicals.
Question by: Cheryl on Aug 2, 2022, 9:00 AM
Soaking your rocks in Flatworm Exit will not harm the rocks but it is doubtful it will have a positive impact on them either. Depending upon how long your rocks were out of the system and water, any existing flatworms may already have died. If you have the opportunity, and if you are planning on cycling the tank again, you can leave your rocks out in the sun for several weeks and that should kill off anything that might be present (that does include anything that might be beneficial).

Would this product work to remove Polyclad flatworms from my tank?
Question by: James O'Donnell on Dec 30, 2016, 12:07 AM
Great question! This will not effectively remove that type of flatworm. Although it may agitate them, most reports from users state that it isn't a viable solutions. Unfortunately, we haven't been able to test all of the methods available, many users on the reef hobbyist forums have had success with other approaches. :-)
