Aquarium Advice Regular
I was told that Goldfish require and favor a highly oxygenated tank. This being said , do my live plants rob them of this precious element? Any help would be appreciated?
When the lights are on they will produce oxygen and use carbon dioxide, however when the lights are off they do use oxygen and in highly planted tanks (or tanks with greenwater algae) it is possible to create dangerously low oxygen levels at night. Any goldfish tank should have air stones run by strong air pumps. This alone will prevent any problems.
