Which is why I want to encourage my chaeto growth
As I understand it, iron will make the chaeto grow faster than the microalgae in most cases. I assume this is because macroalgae can absorb the iron better than microalgae. The chaeto should also absorb the other nutrients during this growth process (especially phosphate). This all allows the macroalgae to outcompete the microalgae. I know this is not always the case, and iron can make an algae problem worse. But if you keep an eye on things, this should not be an issue because you can always stop the iron supplementation.
I plan on giving it a try.
