i'm replacing the Red Flourite in my 75G with Eco Complete so i have to uproot HC and replant it. some of leaves have algae (dark blue-green looking, not sure if it is cyanobacteria) on the surface so i want to take this opportunity to get get rid of this nasty thing. has anyone tried dipping HC into Hydrogen Peroxide or any kinds of chemical to kill algae? i have dropped HP on top of the leaves before and they seemed unharmed by it but they were in the tank with water. i'm worried that HP might destroy the root hairs if i dip the whole plant into the solution.
