what does caulepra and cheato remove?

[fishykid9212]

What are all the things they remove from the water, that make a refugium worth having?

[Fredfish]

Nitrates and phosphates.

Refugiums are also useful for growing pods and other micro-critters as food for the main tank.

Some also find them pleasing to look at.
