I don't have a drain only the overflow on the back. If i put filter floss in the first stage and carbon in the second, and changed both every couple of days, would this accomplish the same thing?

I have tried everything in the past and this is the only thing that works. I even bought 3 blue velet nudibranchs only to enjoy them for 1 hour before they disappeared.

Now the trick to using flat worm exit is to do a dose every couple of days for a week. After your first dose you won't see them for a couple of days and think they are gone only to have the little buggers pop up again.

On your first dose make sure you try to get as many out as by first syphoning the tank. After that, put a filter sock on your drain and use 1 & 1/2 of the reccomended dosage (found that using a wee bit of a stronger dose worked better). This is when you will see the little guys let go of the rocks and start floating around in the tank. Let the tank run for a few hours and take the filter sock off the drain and rinse it off. Wait 2 days, dose again, than 2 more days, and finally 2 more days. after this you should be clear of all flat worms.
