What's the difference

[Nakie31]

What is the difference between copepods and phytoplankton?

 

[Animagus]

One is a small crustacean while the other is basically just microscopic plant life.

 

[Nakie31]

Can the both be used in the sump?

 

[Animagus]

Yeah, you can add both of them to the sump if you want, but the phytoplankton is usually used in small doses over a certain period of time. Don't dump the whole bottle/culture in all at once.

Can the both be used in the sump?

What are you trying to "use" them for?

 

[Ron Reefman]

In a mature sump or a cycled refugium, copepods can reproduce and be self sustaining. Phytoplancton will be short lived and you will always be adding more. Some people keep a separate Phyto 'culture' going to feed the DT.

Many people don't use phyto at all: it can contribute phosphate, and copepods can get by on a cheato culture in the sump.
