What to run in my reactors

[BDV0128]

I just set up a 90 gallon tank with a 30 gallon sump. I have a refugium but no Chaeto yet.

I also have two media reactors. I was wondering what I should run in them. I was thinking carbon and bio pellets.

Carbon gfo zeovit and even co2 scrubbing materials can all be ran in media reactors.

Nothing... Until you need something

I agree with above.
Don't understand why people buy or run equipment that they're not sure what to do with or even if they even need it.
