Exclamation Black carbon dust in water after carbon change (Kinetico 1100 Dechlorinator)

The issue:
Black water (carbon dust) in water after changing carbon medium.

Equipment:
Kinetico 1100 Dechlorinator (10x54)
8 x 16 Mesh Acid Washed Activated Carbon Media
Dechlorinator 1100 | Water Purification Systems - St Louis

Carbon Used:
GCS-1240 Aquatrol Coconut Shell Granular Activated Carbon
https://www.uswatersystems.com/aquat...ed-carbon.html

Questions:
  1. Is black water a normal occurrence after replacing carbon medium?
  2. If you view the spec sheets attached to the pages above, can you tell me if I am using the wrong carbon?
  3. Or am I worried too much and should just continue flusing through the pipes?

How much black/dusty water are you getting and how long have you flushed the system after your media change? Some dust is normal but it usually clears up within a couple minutes.

It's pretty thick and heavy in certain locations. The sinks seem to be less than the toilet and bathtub for some reason. It didn't start immediately either. About 10 minutes after turning the water back on. I do have to state that the carbon was pretty dusty when pouring it in through the funnel.

-Would inadequate amount of gravel bedding cause this?
-Is it a sign the riser is bad?
-Will the dust eventually wash out?

My water system set up:

1) Pump to the
2) Well Mate Tank through the
3) Chlorine Injection (although currently disconnected) to the
4) Kenetico 1100 Dechlorinator to the
5) House/Hot Water/etc/

Should have opened up the outside faucets if there connected to the to that filtered line.
If not then the aerator on the faucet closest to the filter should have been removed and the line flushed.

A normal regen will clear the water of the carbon.

Toilets and bathtubs seem worse because you can more easily see the particulate in the water. The delay in seeing the dusty water was probably because the water lines in your house contained clear water from before the charcoal change. Once that water was purged from the line you started seeing water that had gone through the filter since changing the carbon.

Wink Follow Up and resolved: Kenetico 1100 Carbon replacement/black residue in water

Thanks for the quick responses. After flushing for an additional 5 minutes, filling the filter up with water and letting sit all night, and then running this morning it seems like I am all cleared out.

I think, after I filled the Kenetico 1100 with the gravel base and carbon, I should have filled with water and let the carbon soak up the water while initially bypassing the Kenetico. It was just a dusty mix and running water through the dry mix took awhile for it to clear out.

Lesson learned! Now to cut some pipes and get this Stenner chlorine injector installed.

Thanks all!

And just a side note for anyone in the future...it took about 30 minutes to clear out the residue.
