Korallin S-1502

[easplund]

I just received a Korallin S-1502 Biodenitrator and set it up according to the directions. It has a length of green tubing coming out of the top with a valve at the end of it. What is the purpose of this tube? Is it to allow the nitrogen to escape? Should the valve be open or closed?

I am in the process of setting up the same reactor. I bought it used but was told that it is indeed there to purge gas while priming.

Hello,

Thanks for the post easplund, yes the purpose of the tube is to remove any accumulated gases from the chamber, You should only open the valve to remove the build up of gases.

I hope this information was helpful to you.

Thanks for your help Engine 7

How will I know when the gasses have built up to the extent that they need to be bled off? Do I just open the valve for a few seconds every week? If the reactor is pressurized, won't water squirt out of it?

Hello,

Thanks for the reply, it's always best to remove any type of gas build up you may have, you should be able to look at the top part of the reactor underneath the lid and see if there is any build up. It will vary on how much build up you may or may not get, but usually it is very little. To remove any excess gasses you will need to slowly open the valve until you get a small amount of water coming out of the valve, then immediately close it.
I hope this information helps, please let us know if you have any further questions

Ok, the directions say that after running for a week, turn the output back to one drip every two seconds and test the NO2 in the output. If there is NO2 in the output (mine was off the scale), they don't say what to do. Am I supposed to just leave it at the one drip every two second rate and test daily for NO2?

Hello,
Thank you for your response, you will need to keep the reduced effluent drip rate to 1 drop per every 2 seconds and test again with in the week. Once the N02 is at zero you will need to change the effluent drip rate to 1 drop per second. Allow the BioDenitrator to run for 24 hours then test the NO2 level and NO3 (nitrate) level: both in the aquarium and of the effluent.
Please keep in mind that it usually takes 4-6 weeks for the colonization of the denitrifying bacteria in the media.

I hope you find this information useful, feel free to contact us with any further questions you may have.

It has been another week and a half, and there was no nitrite in the output of the unit. I adjusted the drip rate to one drop per second, and I will test the nitrite and nitrate this evening. However, I noticed that the effluent smelled like sulpher. The odor was noticable even from the drops as they dripped from the output valve. Is this normal?

Hello,

Thanks for your reply, it is normal for the effluent to smell like sulpher while in the begining stages.
