Reactor flow rates

[palvyre]

I was thinking of setting up a carbon/gfo reactor for my 180. I am getting a 500 gph pump for my UV loop and I was thinking about putting the output from the UV sterilizer into the reactor ... Is that too much flow?

For carbon, you should be fine. As for GFO thats probably too much. You just want the surface of the GFO to tumble slightly. Otherwise you will blow it out of the reactor.

Guess I can add a separate reactor for gfo later and use a smaller pump with a ball valve.

I was also worried about it being too much for the carbon, since I know if the media is pushed into the display it could cause issues with my fish.

I have my carbon and GFO running in line. The carbon is first since flow doesnt matter that much. Then I have a ball valve between the reactors to control the flow to the GFO. Also Chemi-Pure Elite is a great product that combines carbon and gfo together.

Anyone use the BRS dual reactor? Looks nice and easy to setup.

I have one. Dont use it anymore because it does not have enough flow for me. But I was trying to use it for biopellets. It may work good for carbon and gfo.

With the dual reactor if you change your carbon/gfo as recomended then your carbon gets changed out before gfo and with a dual reactor you'll need to handwash the carbon or else you'll wash the dust into your gfo or tank or if u put the output in a bucket just a waste of tank water imo. The single reactors easy to take to my ro/di unit and use that pump in resevoir to clean the carbon and empty into sink or bucket. Just seems easier to me.

Good point Mike. Rinsing and changing out the media for carbon and gfo gets to be a PIA real quick. I am running both carbon and GFO in one reactor, but only using a quarter of the GFO suggested amount, so I just change it all out every 4 weeks.

 

[palvyre]

You can put both media types stacked in one? Which do you put in first? And what flow rate are you using?

 

[Dowtish]

Yes, they are just mixed together. And i'm using a mini jet 606 pump. They run about 160 gph, and I have a ball valve on it to slow it down. All you want is just enough for water to flow through the media. just a slight tumble on the surface.

 

[palvyre]

Wonder if that is enough to do any good on 180.

 

[Dowtish]

The amount of media will determine that. Not the rate of flow,that will stay the same. You will just need a larger reactor if you want to run both at the same time.

The brs single reactor has a sponge to seperate the carbon/gfo if ran in same reactor that way gfo can tumble while carbon doesn't. But its not the tumble that matters with gfo long as it stays fluidized so water can go around the media and not clump up.
