I'm trying this - how long does it take to nuke the worms? One is still attached to my tilapia's snout, and wonder how long before it gets killed as well as the ones on the glass walls ?
It's been a few hours - still see the worm on the fish, and a couple on the glass. How long does it take for the coppersafe to KILL KILL KILL KILL KILL ? Sorry, but I have DIE DIE DIE on the brain!
