Has anyone ever tracked how fast a carbon can clarify a cloudy/discolored tank?

I'm using 32oz of Rox 0.8 activated carbon on a 105gal system through a reactor with roughly 120gal/hr flow.
 
I can't say I've ever timed it but I expect GAC to at least make a noticable difference overnight, say 12 hours. There are variables and depending on what's making it cloudy GAC may not have any impact.
 
depends on why the tank is cloudy to begin with. fixing this issue first should be priority before using carbon.

The tank is 9 months old and only uses roller mat and a part-time skimmer.

Looking through it lengthwise, it seems to be less than clear with a slight off white tint.

It also seems to have quite a bit of floating dust. This may be due to the DSB (Figi Pink), sand sifting gobies, and 50x tank flow.

I was thinking about getting a UV sterilizer to help with clarification but thought I see how well activated carbon would help.

I add fresh carbon when the tanks starts to get that low tide smell, and starts to get that yellow tint to the water. I run rox 0.8 in a reactor @ 1tbs per 10G. I can visually see it getting clearer in a few hours, and the low tide smell is gone by 24 hours.
