Hi there. My girlfriend has just set up a new tank. She has RO water, and has accidentally overdosed the amount of quick clear. The tank has a kind of film over the plants and ornaments now. There are no fish in, as it is just starting to cycle. Could this overdose cause any problems and is there anything she should do? Thanks for any help.
