Should activated carbon be rinsed first?

[xenon]

I starting using black diamond activated carbon and when I put it in my sump there was a black cloud that came from the carbon.

yes, unless you want a black water tank...:D

Yes rinse it. It helps get rid of the dust cloud you saw.

I sure wish they marineland would print that on their label. :(

Rinse it for about 30 seconds while you swish it around.

Rinse it in RO/di water. You don't want to use the carbon to clean the rinse water :lol:

if your running it in a phosban reactor, pump water from the tank through it and into a bucket for a few seconds, clears very quickly.
