Planaria Destruction

[Aftaburn]

I've recently discovered a couple of things about Planaria as I had several thousand in a system of thier own waiting for me to find a cure (no fish or plant in this tank).

Apon adding 4ppm solution of potassium permangenate the worms started dividing hard out.

This is a 80 liter tank too btw.

Disolved 4 teaspoons of Sodium metabisulphate in a glass & used a syringe to squirt large Planaria (the ones the pp hadn't got too as it settled out a bit), they really dont like it & turn into fuzzy blobs.

Added about another 10 teaspoons to the tank.

Now they're all fuzzy blobs.

I think though knowing how tough the things are that I'll leave the solution at least overnight.

This may not help remove them from a system with fish & plant but it is effective with minimal effort.

Didn't give the permangenate long as they just kept dividing (those that were in the coloured area of the tank divided to the point where they were getting hard to see).
