Fishing Film
I have a red film that grows in my tank of saltwater fish, what is? How can I get rid of it?
If is in the crystal is red algae, but if you're on the rocks or seaweed mud is sand. It is caused by poor filtration, aquarium excessively, or feeding fish. Whatever the case is to get rid of it or keep it at least get some algae herbivores (crabs, snails, sea slugs) and try to limit the you take.
