Do you use carbon?

I was just wondering how many of you guys use carbon.

 

I use it 24/7 and replace it every 30 days. I have it passively in a bag in the sump.

I have in the passed had issues when I stopped using Carbon. I had a few corals RTN.
Prior to running the Zeovit system I didn't use carbon at all and see little difference

I have a Penguin 350 that has carbon in the filter cartridges.

 

Same here.

 

Yes, in my sump, change it every 30 days or so. I also use Chemi-Pure in the sump.

 

I used to...but right now there is no where in my tank where I could put it.

 

I use it every other month. and in the months inbetween I use phosphate remover

 

Yep, I run lab grade carbon (from coal, not coconut) 24x7 in an upflow reactor. I also change it out about once a month.

 

Always have, always will!
