I am a little concerned. I am taking the first steps into switching to RO water. I am planning on having a trash can (13 gallons or so) filled with RO water and an air pump for storage. Should I worry about the plastic leaking anything? Because I know that many plastics have some pretty nasty stuff in them and I don't want that in my fish tanks at all. Anything I should look out for? Do any of you have success with a certain bin? Thanks!
