My friend has an outdoor pond and there are some Lilly pads in it. I dug up a couple and washed them off and put it in my tropical/ native 75 gallon aquarium. I have a FluvalSmart light on the tank and the Lilly grew a slimy film on it. I want to add some to my 125 gallon planted tank but was wondering any ways I can remove any hitch hikers on the roots.
