 |  Denitrator
I have been looking for information on Denitrators. I understand how they work and how to make one, but I don know if I want to because I have heard they can be bad. What are the risks of useing a coil denitrator, and should I make on if my tank(freshwater) is typically boderline on nitrates. I understand that WC's are the best thing, but I have trouble keeping track of when i did them, and remembering to do them. |

O.K I have to ask' Who said the simple old coil is bad or could be a problem ..Been using them longer then I can remember on salt and fresh and never a problem unlike with the sulfur and sugar fed reactors of the last 20 yrs or so.. Problem is they are cheap safe and low tech and will not make anyone rich or famous . And pretty much hands off I think that may be a problem for tweaker geeks ? _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) | |

well then can you make sure i have the basic idea right?? All it basically is is a long hose in a dark environment. Also I think I have read that a black hose is dark enough...is this true?? | |

it works like this,
water travels down the coil (the longer the better) where it is stripped of oxygen by 1 type of bacteria, then it is pushed through the substrate inside the main chamber where another bacteria that requires no oxygen and no light strips the water of nitrates. the water is then sent back to your system where it should be put back into your skimmer pick up area where it can be recharged with oxygen before going into your tank.
The flow must be very slow as to allow time for the bacteria to work and not be washed into the tank, but fast enough as to not allow it to become stagnant.
you can run the coil on the inside very time consuming and a challange to get it neat, or you can run it on the outside, much easier and leaves a little extra space inside for more substrate. I will post pictures of the one i built a little later today, it took me about 1 hour with only a drill and a tap and die set mats cost me about 40 bucks not including the substrate.
you can use anything as a substrate some have used hair curlers, bio-balls, etc i went with Ehiem glass beads.
