Hooked up new Denitrator

[Swirlygig]

nice...I don't mind at all...I opened this thread to let others know about de-nitrators as well...

They are great...

Tomorrow is the big day!
We take my denitrator off of my system and install it on Joe's.
Currently my system s running zero nitrates tested on a colorimeter. This will be a learning curve as how to properly transfer from one system to another and hopefully back. There are always concrns of pests and other forms of bacterial issues, this will also be watched closely.
I currently run my unit at a slow steady stream and we will be starting Joe's at 60 drops per minute as a reference and testing every 6-8 hours until properly adjusted and reducing nitrates as expected.
Keep posted for the results.

I just set up one of David's de-nitrators. My Nitrates tested yesterday at 50ppm as a starting point. I will post the progress. Currently I am running the de-nitrator at 25 drops per min

Hey Brad, glad you could join.

 

[magrath]

Thanks for all your setup help David. I tested the effluent after 24hrs of setup and it was 40ppm so I uped the flow to 40 drops per min. I will update again tomorrow when I test.

 

[magrath]

Well I was out yesterday so I did not get to test until today and the effluent was 160ppm. I have increased the flow to 160dpm. Hopefully it will start going down rapidly.

 

[skinnyjoe1976]

well mine has drop below 40ppm in 36 hours. keep in mind that it has been established setup. i'm a month ahead of the water changes to fix it.

 

[davy182]

That was diffinitely the noticeable increase in nitrates before you adjust it to the next drip rate Brad. Good to see that it is working accordingly.

 

[magrath]

I tested today and it was 80ppm. Should I adjust the drip rate or should it continue to go down before I increase the drip rate?

 

[davy182]

You adjusted to 160dpm right. What is the tank water at? At 160 dpm you could leave it there till the nitrates are close to zero.

 

[tricky]

Would this be a good idea for a FOLR tank? Tried about everything else to get and keep the nitrates down - it's an older tank.

 

[davy182]

Should do just fine. I would probably go with very little aragonite though since it is a FOLR tank. That way the calcium doesn't go through the roof. The only thing you need to do is dose baking soda for the alkalinity uptake from the nitrate removal process.

 

[magrath]

I am still running 160dpm. I will test again tonight and post the update.

 

[magrath]

I tested it last night and again this morning and it is staying steady at 60ppm with a 160 dpm. Should I keep it at 160dpm until it goes down some more?

 

[davy182]

yes just leave it there and it will keep lowering it.

 

[davy182]

It should gradually keep getting lower. If you notice no drop over the next day or so back it down a little to like 120dpm.

It took mine a bit to kick in...I had to back mine off and play with it a bit...Sometimes it takes a while...
