Flatworms won't die!

When did you do your water change?

Wait till you have completed a week of dosing FWE, also take your carbon out during this time. Run carbon after your first water change.

I disagree with the above comment. I wasted $60 on nudibranchs only to enjoy them for a few hours. There are a few wrasses (melanurus) that actually eat them but it is sometimes a hit and miss.

It didn't have an impact on my tank, my sps colors are still bright and my growth hasn't slowed down.
