deltec denitrator

[the captive reef]

hey everyone,

Here is a never used deltec sulfur denitrator. I purchased from the UK a couple years ago and never hooked it up.

Picture:

Price is $125 shipped

thanks,

mike

does it come with pump ? If so, what kind ?

 

[the captive reef]

No, you will need a very small pump to feed it:

these would work well:

Here are the instructions if anyone want to read them:


INSTRUCTIONS FOR THE SULPHUR NITRATE FILTER Suitable for freshwater and saltwater up to Up to 400/600 litres Important Principles Operation of the Sulphur Nitrate filter is based the natural principle of REDUCTION of nitrate NO3 to nitrogen gas N2 using a colony of anaerobic bacteria in a low oxygen environment. It is important therefore to understand that for the unit to work you must create a STABLE bacterial colony and if you allow too much air rich water into the reactor before the colony is stable then it will crash and you will have to start again from the beginning. The bacteria require a food source and oxygen to survive. The food source is the sulphur and as they are anaerobic bacteria and only grow in the low oxygen water they must obtain the oxygen from another source. The bacteria take the oxygen from the nitrate molecule by reduction, first from nitrate NO3 to Nitrite NO3 and then further from nitrite to nitrogen gas N2. When the unit is new there is a tendency for the first colonies of bacteria to be the aerobic type as the water is still oxygen rich. These bacteria will act like normal oxidising bacteria turning ammonia NH4 to nitrite and nitrate therefore initially you may see an increase in the nitrate level. The aerobic bacteria will use up the oxygen in the unit and create an environment in which the anaerobic bacteria will start to grow. Initially the anaerobic bacteria will only partially reduce the nitrate to nitrite and you may detect this however the bacteria within the tank will turn it straight back to nitrate. Finally the oxygen level, (redox) will be low enough in the reactor for the bacteria to convert all of the nitrate to nitrogen and it is time to slowly increase the flow. Installation Hang or stand the Sulphur Nitrate NO3 filter vertically in a sump or beside the tank. Note: The NO3 Filter can only operate in the vertical position. Always put the Micro-Filter on the inlet to the reactor to stop the tap from blocking and always control the water volume on the way in and not on the way out. Commissioning Flush through the reactor with water before use to remove all dust particles and throw away this water. Connect the reactor to the output of a main sump pump by means of a bypass, small independent power head or alternatively gravity feed the unit from the main aquarium into the sump. At all times ensure that the siphon can be broken in the case of a power failure. The water from the output can simply drip directly into the aquarium or the sump according to the installation. Settings Fill the unit with water from the aquarium and switch off the tap. Leave the unit to stand full of water for 3 days to allow oxygen within the reactor to be used up. CAREFULLY open the tap and regulate the flow rate at the outlet to one drop per second or lower if possible, but not less then one drop every three seconds. Measure the Nitrate concentration at the outlet after four days. If this has not dropped to zero wait until it has done so. This can take up to 10 days or longer, especially when the temperature is low, near 17 C and if the nitrate is below 25 mg/L. Once you have had a zero reading for over two days, you can increase the drip rate slowly by about 25-30%, (we accept that initially this small increase is not easy to assess). Wait again for a zero reading for two continuous days and than increase the drip rate again by 25-30%. Wait again until you have two days of zero nitrates and then increase again and so on. Ultimately you will get to 7 litres per hour, then 8, then 9 litres per hour until finally it is possible to increase the rate to 10 litres per hour. We recommend as the flow increases that you wait four days with zero reading before moving on. The Filter is now commissioned. Information It is possible under the right conditions to further increase the performance of the Nitrate NO3 filter up to a maximum output of 15 litres per hour when there is a high concentration of Nitrate NO3 in the water, however you should be aware that the PH coming out of your Nitrate filter will be very low and for small tanks it is better to run it slowly. The Nitrate will fall but it will take a little longer and will require less buffering. Buffering: The water leaving the NO3 filter has a very low PH, approximately 6 to 6.5, or lower in fresh water. This water can be dripped over coral sand to raise the PH before entering the aquarium, or through a container with an air stone in it. This is particularly important on fresh water as coral sand could harden the water. If you exceed at any time the maximum flow rate until the bacterial colony can deal with it then you will add oxygen, raise the redox and the system will crash requiring you to start again with the above procedure. Maintenance to Micro filter It is important to regularly flash the Micro filter trough with vinegar to maintain constant flow. Replacement Micro filters can be obtained from your nearest retailer. NOTE The bacterial colony will not grow below 17C and will increase considerably at higher temperatures.

PLEASE CLOSE THREAD SOLD!!!!

 

[Spiderwoman]

Thanks for the shipment Mike!

Question:
What type of media have you ran in it? Do you recommend any brand over the other? I'm going to order the media today.

Thanks!

 

[the captive reef]

Hello,

Glad you got it OK. It has sulfur media in it from deltec. IT HAS NEVER BEEN USED, so the media in there is fine to use.

Let me know if you have any more questions,

thanks,

mike
