So you are saying that over time the water chemistry will not change in the closed system like a reef tank ? This is called setting up a "straw man". No. I am not saying this at all. You were questioning the reason to change water based on nitrates... You know, there are much more different ions there beside NO3-... Yes, I am aware. Then you are probably aware also, that 80% of their levels you cannot measure at home acuratelly. With partial water change you replenish ions used up by growing animals/plants in your tank. I add trace elements (Kent Marine Essential Elements) on a monthly basis. Each element is used up in a different speed, but you dump all of them on a monthly basis regardless if you need it or not. That will lead over time to chemical imbalance and your tank water will be far, far away from the content of natural sea water compared to the water mixed from the fresh salt mix. You also remove organic byproducts your skimmer left behind. Such as? All these which make your water smell and look yellow. Corals, other invertebrates, fish and plants constantly release many substances to the water which accumulate in the closed system like an aquarium. You are not able to measure them or detect them in home situation... Changing water refreshes the water and brings it back to its original ionic combination... Would you be fine if your house was perfectly sealed from the outside air and you just reduce amount of CO2 and add oxygen on regular basis but would not exchange air for years? How do you think your house would smell ? :-)) |

Do these things "work?" That is, doesn't the nitrate have to turn into something?! What is the waste product of the de nitrifying bacteria? A web search turns up several articles. Basically, the denitrator is a bacterial filter that contains cultures of bacteria that eat oxygen. These bacteria remove the oxygen from the NO3, producing free nitrogen as a byproduct.

wrong. N2 and H2O
Where's the hydrogen come from? See my response to Pszemol. You can split two NO3 molecules into one N2 and three O2 molecules. Who/what can? The NO3 is broken down enzymatically. The enzyme(s) do not split NO3 into N2 and O2. George Patterson Coffee is only a way of stealing time that should by rights belong to your slightly older self. |

-- You were questioning the reason to change water based on nitrates... I am not questioning anything, I am answering Adam's (the OP) question. See above in the thread. You know, there are much more different ions there beside NO3-... Yes, I am aware. Then you are probably aware also, that 80% of their levels you cannot measure at home acuratelly. 80% of what levels? Can you be more specific? Doesn't how accurate you need to be depend on the ion you are referring to? With partial water change you replenish ions used up by growing animals/plants in your tank. I add trace elements (Kent Marine Essential Elements) on a monthly basis. Each element is used up in a different speed, but you dump all of them on a monthly basis regardless if you need it or not. How do you replenish your trace elements? Partial water change? When you do your partial water change you are removing some percentage of water (15-20%?) and adding artificial sea salt (usually contains trace elements). How do you know your tank needs it (trace elements)? That will lead over time to chemical imbalance and your tank water will be far, far away from the content of natural sea water compared to the water mixed from the fresh salt mix. You are FAR MORE likely to cause a chemical imbalance by replacing a percentage (15-20%?) of your aquarium water with home made sea water than you are by doing no water change. You also remove organic byproducts your skimmer left behind. Such as? All these which make your water smell and look yellow. Corals, other invertebrates, fish and plants constantly release many substances to the water which accumulate in the closed system like an aquarium. My skimmer runs 24hrs a day. The organic compounds it doesn't remove on the first pass will more than likely be removed on the second, third, fourth or fifth, etc. pass. You are not able to measure them or detect them in home situation... Agreed. Therefore, I have NO reason to question my skimmers effectiveness. I can only go by the health/appearance of my tank mates. They are doing fine. All is well. My water is not yellow and it does not smell. Changing water refreshes the water and brings it back to its original ionic combination... The only way YOU would "bring it back to its original" condition is if you changed 100% of your water. Is this what you are doing? If this is what you are doing you are doing more harm than good. Would you be fine if your house was perfectly sealed from the outside air and you just reduce amount of CO2 and add oxygen on regular basis but would not exchange air for years? Another straw man. How do you think your house would smell ? :-)) I do not have microorganisms that eat and decompose my excrements, my aquarium inhabitants do. |

LOL this is a reef newsgroup, not a fish only newsgroup.
That's right, I have a FOWLR tank, nevertheless, my comments are still applicable. |

A web search turns up several articles. Basically, the denitrator is a
bacterial filter that contains cultures of bacteria that eat oxygen. These bacteria remove the oxygen from the NO3, producing free nitrogen as a byproduct. So very wrong, but so close. The denitrator sets up an anaerobic environment (oxygen depleted) for the bacteria to thrive that break down NO3-, it's called denitrification. These anaerobic bacteria contain enzymes that break down NO3- into N2 and H2O.
