yesterday i noticed my co2 was running low so turned it up at little and this morning the co2 was empty as expected but i had 3 dead noen tetras (4 others were fine) i dont no if this is because of the co2. I tested the water and found everything to be normal and there was a oily film on the surface does anyone know what happened as i dont think it was the co2.
hope someone can help
