RODI Filter Changing

[nyc reefer]

Help, my RODI uses 2 large carbons after the sediment filter. I need to know which one goes first?

0.6 micron and 1uM

Thanks

watch a video about cartridge changing at bulkreefsupply. they say which one is first
hope im not breaking rules by saying where the video is!

the higher micron goes first, the lower micron second.
