kien's 150g Room Divider Mixed Reef & Stuff

[kien]

I typically only run a cup if rox 8 in one reactor that I change once a month. I'm just trying out a new system where I run half that amount (1/2 cup) in each reactor and replace one every 30 days. So, reactor 1 gets swapped out on the 15th if every month while reactor 2 gets swapped out on the 30th. The goal being a better transition from spent to new carbon. Just something to do I guess
