Adding carbon and GFO reactors to UV output?

[Sharkey18]

Any reason this would be problem? As long as the carbon is NOT tumbling and the GFO is gently tumbling. I will be using two canisters.

 

So it would be pump --> UV --> carbon --> gfo --> sump.

I think you would find you have to split it coming out of the uv so not all the flow goes to the gfo/carbon. The UV is going to require much higher flow rate to be effective than the gfo/carbonn I'd guess. Otherwise it should work fine.
