Sweet. I'm going to check out RCA today for one

I like the BRS ones. Really easy to use.

I'd be careful about running a mix of carbon/GFO together Jimbo. Carbon dust has been linked to lateral line disease in tangs and GFO needs to tumble to be utilized most efficiently. Basically a single reactor, if you tumble, you'll get the most from GFO but release carbon dust or vice versa, if you don't allow to tumble, you won't create carbon dust but your GFO will not function as efficient. I'd just run carbon passively in a bag in the sump. Just as effective IMO....
