out of curiosity how many people here run nitrate absorbing products?

[Bob 1000]

What it's doing is taking a portion of the nitrate loaded water out of the tank and using the nitragone(methanol) dosed into the denitrifying reactor to eat up the nitrates in the water and then flushing nitrate free water back into the main tank...And if you have the phosphate option on your reactor it doses something to eat phosphates up while eating nitrates at the same time...Doing this cycle 4x a day gives you the benefits of doing up to 6 water changes a day..Pulling a certian percentage of nitrates out of your water daily..All but eliminating the need to do frequent water changes while having an overstocked tank....

Oh, methanol(Nitragone) fed to anerobic bacteria speeds up it's ability to eat nitrates allowing it to reproduce faster and cycle(eat up) nitrates to 0 faster...

ah, ok that helps

thanks!

If you need more info just let me know...I think this was the best purchase for my tank...A lot of people don't have them because they don't understand the benefits of this thing...Yeah it cost almost $800...But I have figured out how to build my own for a lot less...

i use xenia, dropped down my nitrates to 0, no joke... i have no fuge and feed well everday!:tongueani

you can just build a DIY coil denitrator for under $100 also

thats what i did

If you test the water coming from that drip, It'll read 0...:scratchch

Warren, why is it everything I do in this hobby, you've already done, lol.

I'm getting my de*nitrate in tomorrow, approximately what gph is a steady fast drip? They say no more than 50gph in the seachem forum but I was planning on doing something like 30gph so my tank gets turned over 2X an hour. I figured I'd do the de*nitrate instead of a remote dsb, do you really think its as effective as seachem says?

I'm getting the 34oz / 1 liter jar, not sure if it will all fit in on phosban reactor but thats what I was going to try to do.

:lol:

I have this on a 120g which is heavily feed. Utilizing the 2nd size MRC (cali :theyareon ) fluidized reactor with the inlet and outlets reduced to RO tubing size. Reactor is pressure fed from a tee off the main return pump and is dripped back into the sump. I've been using a "fast drip" as opposed to a slow drip such as in the case of coil denitrators or even with the sulfur based Korallin denitrators. So a fast drip to me is when the flow is a broken stream but right before it becomes a steady stream. Don't forget that this RO tubing (1/8").

My No3 was between 25 and 50 ppm before I started 3-4 weeks ago and I just tested yesterday and it's down to 2 to 3 ppm based on a salifert test kit. It's subjective due to the test results being compared to a color chart but with the large difference, it's noticeable enough on the lowering part. The reactor is packed from the top of the sponge to the bottom one as well. I used almost 4 liters.

Thanks Warren.

Is any introduction of air disastrous for the de-nitrification bacteria? To clarify I'll explain my setup. I have two phosban reactors in series. The first has carbon, then rowa and the carbon. That outlet goes into the second phosban reactor which is filled with de*nitrate. I was concerned about the bubbles from my skimmer entering into the phosban reactors or if I ever made the mistake of taking out the feed pump, a minijet 404, which would introduce air. Secondly I have the water flowing thru much faster than a drip. Less than 50gph but probably around 20-25. Will this hurt the process? Seachem says as long as its lower than 50gph it should be okay.

BTW, that commute really sucks!

Paul,

I don't think that if air enters the reactor, that it would be disastrous because my reactor always has some air within due to the slow feed.
You should post this question on the S-chem forum for confirmation though.

I was under the impression that an anerobic enviroment was ideal in creating nitrate eating bacteria... With my reactor if air is aloud into reactor before the process is over(denitrification)...You get regular good bacteria not denitrifying bacteria...There are warnings of this on the manual that comes with my unit...
