I bought a fluval cannister filter about two weeks ago, and since replacing the HOB a film of something has formed on top of the water. any ideas what this is?
i went through this about a month ago. i also inject co2 for plants, i bring it in through the smaller sized air stone which goes in to the intake of a power head (does a really nice job of producing very small co2 bubbles).... other stuff
