Sulfur DeNITRIFIER DIY!!!

hey melev just a comment, are you using filters just like in the photos above for your denitrifier, if so then the water is not getting thru the media thus not creating an anaerobic zone, you will have to put pieces of pipe in the middle of those filter tops to force the water to go down into the media and then up, just a tought

The water goes down around the canister and then up through the refillable cartridge / media to exit to the next chamber.

I'll test nitrates in a few minutes.
 
melev, does it have a pipe in the center of the top of filter, i am asking this because i have been in the water bussiness for a while and used those type of filter housings, but if you dont put a pipe in the center water will enter canister but it will just come ot right away without forcing it thru the media, let me make a drewing to better explain it
 
That isn't how this is set up. Water enters on the side through a smaller hole, then fills the acrylic housing. Water must exit through the refill that is sealed tighted with a flat washer against the upper plate. Water is indeed passing up through the media, just like it does in a DI application.

It does NOT pour down through the center, although it would be easy to assemble it the opposite way to achieve that.
 
ohh i get it, so there are refillable cartridges with the sulphur media inside, and the cartridges are inside the filter canisters, so water is getting forced thru them.....

i am using a phosban reactor which has the same principle i am trying to explain, lol
 
melev do it just like you have pointed out, your system is not creating that anaerobic zone because water is not going thru media the proper way, imagine a phosban reactor but with your filter canisters
 
here are a photo with some lines (excuse the drawings)
this is the set up i think you have right now, yellow is water and blue is the media

and this is the same setup but with pipes in the middle, yellow is water, blue is media, brown are the pipes, water is beign forced thru the media

hope this helps
 
Mine is going from the right side to the left. It goes in and over the sulfur, not through it. Then it goes down and through the ARM, and down and through the carbon, and exits.
 
This is awesome!! Maybe I should start feeding my tank like Marc does so I can actually get a nitrate rating :P JK Marc! I would never do that, I like my fish miserable and my corals happy. LOL <3
 
the water has to go thru sulfur, ARM and through carbon for the system to work, if it just goes over the sulphur then its not going to create an anaerobic zone within the media
 
When I first set it up to push water into the sulfur, the tubing actually was sucking up the sulfur orbs (because of the way the flow runs through the caps.

The first person to explain this system didn't use any internal canisters.
 
you do need to force water thru, that is the whole basis of the denitrifier, its just the same principle as a phosban reactor, you push water down thru the middle , then up from the sides forcing the water to go thru the sulphur media, thus making an anaerobic zone within the sulphur media, if you dont do this your denitrifier will never cycle.

if media was beign sucked thru the tube you can cap off the tube on the bottom and make little holes on the bottom of pipe, just enough for water to get through but stop the media from coming out

Or I could reverse the cap on that one so I can flow water down into the granules.
 
you could reverse the flow, but you will still need the pipes on the caps of filter housings to force the water thru, if you do this it will work or i will quit my job and move to a far away land
 
it should haved cycle by know, so if you want to try

1 reversing flow on filter canisters, in thru middle, out thru side
2 installing pvc pipe in the middle of the filter endcaps
3 since theres little flow, i dont believe any media will come out
4 sulphur first, arm second, carbon third
 
ok, here I am with my probs. I installed my reactor(H&S) in my return area two weeks ago and and it kept sucking in micro bubbles. This caused the reactor to stop dripping and I'm assuming stopped any anaerobic areas from developing. Am I right to assume this? I decided to relocate the reactor to an area with less micro bubles and when I did the water in the reactor completely emptied into my sump. Here's my question. Am I starting from zero at this point? and will I "crash" the anaerobic zone every time there's a power failor? I'm confused as to why H&S would design there reactors like this...
 
Why would you have microbubbles in your return section? That zone should be bubble free.

If your reactor drains when the power is off, is this because it siphons out the effluent side, or does it drain out the feed pump side? Perhaps it needs (or has a defective) check valve.
