Thanks, I'm going to go out to the petstore today or tomorrow to get a sponge filter.
Meanwhile I have another question: Does API Fungus cure have copper in it? My 55 gallon planted fish tank got an outbreak of mouth fungus, so I added 5 packets of this stuff, before I read that the Acriflavine kills plants. I have since then been going crazy, I cleaned out 50% of the water yesterday, 25% today, and I am afraid that to much more will put me back into a new tank syndrome. The tank is still green-ish from the medicine. Here's my question: Does Victoria Green B or Acriflavine have any copper in it? I'm asking this because I want to move my plants into my 10 gallon shrimp tank until all the acriflavine is gone. And I have heard that copper will kill invertebrates. Also, does activated carbon remove this plant killer (aka acriflavine)?
