Question - Korallin biodenitrator S1502

[beachsidereefer]

Hi Folks,

So I got this used reactor with my 200 gallon tank, cleaned it up, put in fresh media, primed and got the thing working. Right now it's doing about a drop of second back into my sump and with the valve all the way open it flows a decent stream of water. The pump seems to be humming right along but I don't see the yellow media tumbling. My question is should the media tumble like I see in youtube videos for other brands of reactors? or is this type of model designed not tumble the yellow media?

Thanks,
Orson.

sorry, forgot to mention I did shake the reactor a couple of times and the media does not appear to be frozen up.... it will definitely move around if I shake it.

wow, no replies again! two threads in a row I've completely stumped the experts on here.

Denitrators don't tend to run any kind of flow through them. So there woudln't be any tumbling media to my knowledge. The water flows throughly down all the media where the bacteria is growing to remove the Nitrates, thus its going to be very slow. When I ran mine it was at 3 drips per second. Not quick at all. Sulpher denitrators run a bit quicker.
Sorry for the late reply, missed it.

Thank you for the advice. I agree with your line of thinking but then I saw a couple of youtube videos where they show the sulfur media tumbling along with a valve to adjust the tumble so I started to wonder how the one I have should work.

Right now I have it going at two drops a second which is what the instructions recommended.

I have the same biodenitrator and absolutely love it! The sulfur beads are not supposed to tumble. I have mine running at 2 drips/sec. It did take the full 6 weeks for mine to kick in. Ialso have the prefilter to reduce amount of build up inside it.

Thanks buckroe07 for the information. How often do you change out the sulfur media? I'm guessing the reef bones never have to be changed out unless they completely disolve?
