Well Flatworms are finally gone... All I can say is flatworm exit is some powerful stuff!
Directions talk about 1-2 hours if no effects are visible, add some more... Well I figured that meant it would take some time...
2 minutes after I added the 2 drops of FWE - the flatworms were dead/dying. 5 minutes later, the tank was yellow.
15 minutes later the tank was a nasty orange color.
Don't be fooled - this stuff works quick, be ready the instant this stuff goes in...
If anyone in calgary needs some - speak up, ended up bringing in a bottle from aquaria.ca; I've used 2 drops of 300
