Kent
about 2 cups for 180 gallons in a phosban reactor
changed every 2-4 weeks (depending on when I remember)

+1 for Kent Reef Carbon

Kent
2 cups
180g in BRS reactor
4 weeks

BRS lignite carbon
1 cup in a TLF reactor
replace once a month
+200gal total system volume

BRS ROX .8
1 cup (ish)
Once a month (ish)
321g total water volume (ish)

NO CARBON used here...

Maybe every couple of months I stick a white card in the tank to let me know if the water is yellowing over time.
If so I use Kent carbon and stick a cup or so in a bag in the return and leave it there for a day or two.
The carbon removes the yellowing.

I use that fluval carbon fill up a Reactor and run it well lord knows ..... i buy mine through BWI in Ontario. total volume 175 gals

Kent
2 cups in a BRS reactor
changed once a month

ROX 0.8 2/3 cup. Replace monthly.

I use Kent, want to try the Zeovit, but it is always on back order. Kent has worked fine for me.

1 litre for 180G display and 105 G refuge - actual water volume is less

I replace once a month

I would guesstamate about 225G of water

box from Aquagiant (~2cups) placed in mesh bag in high flow area of sump, try to remember to change monthly, 200g system.

Kent. 2 cups in a TLF changed monthly/when I remember.

150ish gallon system

No particular brand. whatever I can find cheap.
I've tried SeaChem Matrix, Kent, and currently on a can of Marineland.
Only difference I've noticed is price. so I gave up and just buy the cheapest one.
A little extra dust isn't a big deal, just rince it longer.

Use 1.5-2 cups along with a cup of purigen (separate bags) inside an eheim 2213 cannister.

Change every month or 2.
