Activated carbon reactor

Other than hanging a bag filled with carbon in the sump,
what do you use to make carbon work more efficiently?

Tha idea with a bag works, but in my understanding
water would penetrate carbon better if it was flowing
forced through not around the bag...

I was trying to put a layer of carbon in the phosphate
reactor, but carbon is very light and it is easily
lifted up with water and travels back to my tank...

How do you put carbon to work in your reef tanks?

Now I have an idea... what if I dump the carbon loose
into the sock in the sump? The sock I am using is quite
fine to prevent carbon escaping to the sump and the
water is pretty well agitated in the sock so the carbon
will work efficiently there...
The sock lasts about a week or two before it clogs
with dirt, so I could dump the sock with used up carbon
to the garbagge and put new sock with new carbon portion.
Sounds like a good idea - have to test it :-)
