Another question that I am frequently asked:
Do I need to add extra iron?
If you are dosing CSM+B or Millers Microplex then you are already adding iron. For most tanks this will be enough. However in high light tanks or tanks with co2 injection it is very possible that you will be deficient in iron.
What are signs of iron deficiency?
Iron deficiency will show up on new leaves, causing pale yellow leaves which can become brittle.
