This is Aegagropila linnaei, AKA Cladophora.
Underwater it is an awesome, green ball of goodness. It can also grow on wood.
So I though, 'Hey, lets try this stuff emmersed in my vivarium!'
This is emmersed Clado:
Brownish, Greenish, Grey puke. ITs ugly. Its spreading fast. And I cannot kill it.
Normally I would use glutaraldehyde to kill it in an aquarium. With sensitive frogs in the tank, I don't dare use a harsh chemical!
Help would be appreciated before my tank turns to fuzzy puke!!!
