SRC Member mopiko Posted November 19, 2007 SRC Member Share Posted November 19, 2007 as above. any reefers using Nitrate Reactors? how effective is it? its an expensive toy to have Quote Link to comment Share on other sites More sharing options...
SRC Member reeftask Posted November 19, 2007 SRC Member Share Posted November 19, 2007 not too expensive and not too cheap either. If tuned nicely, will be a good help. But problem is you have to tune it very frequent and its not so easy to tune. Most owners gave up after so much time spent on tuning.

fishchemist Posted November 20, 2007 Share Posted November 20, 2007 I got an aquamedic 400 nitrate reductor. I find it very difficult to adjust the flow rate. It got to be slow so that anerobic activities take place but cannot be too slow as hydrogen sulphide can then be produce which is undesirable. Now I'm planning to do a hang on refugium to take care of both the NO3 and Po4 issues. But meantime doing constant water change. Quote Link to comment Share on other sites More sharing options...
SRC Member mopiko Posted November 20, 2007 Author SRC Member Share Posted November 20, 2007 read online that its kinda hard to tune the correct flow rate. reeftask, u know how to tune the no3 reactor a not? or you need someone to tune you instead? i just keeping FOWLR. just don't want the nitrate to get too high. any idea what is the max acceptable ppm for no3 in FOWLR system?

SRC Member reeftask Posted November 20, 2007 SRC Member Share Posted November 20, 2007 Only good looking and young ones can tune me, LOL. I didnt buy it after surveyed the tuning disadvantage. A friend of mine had stubbornly bought it and we tried to tuned it before. Later fedup, he gave it to his friend, LOL. It has a requirement, a drop/certain time depends on your model and brand specifications. Dont waste money calling other ppl to tune. You can do it. Only bad thing, after few weeks, you have to tune again, LOL. Quote Link to comment Share on other sites More sharing options...
SRC Member zipp86 Posted November 21, 2007 SRC Member Share Posted November 21, 2007 well. its not that difficult.. set the drip to 1 drop per second, test for nitrates in the effluent, once you see the nitrates completely gone, increase drip flow slightly then measure nitrates after a few hours. If nitrates is there, reduce the flow, if no nitrates, increase the drip flow. Do this until you can maintain an equilibrium. Quote Link to comment Share on other sites More sharing options...
SRC Member mopiko Posted November 21, 2007 Author SRC Member Share Posted November 21, 2007 haha. i'm good looking and young as well why never let me tune you? is the deltec no3 reactor good and could it be easier to tune? strange not many pple contributing to this thread... think not a popular piece of toy.

SRC Member zipp86 Posted November 21, 2007 SRC Member Share Posted November 21, 2007 which kind? sulphur or anaerobic type? i prefer sulphur, faster results, easy job done.. Quote Link to comment Share on other sites More sharing options...
SRC Member mopiko Posted November 21, 2007 Author SRC Member Share Posted November 21, 2007 think its sulphur kind. where is reeftask? never finish the task here and he go reef liao Quote Link to comment Share on other sites More sharing options...

LOL. So sorry, you bored? LOL. Only gals can tune me, not guys. When a guy wanna come and tune, I will vomit, LOL. You are partly correct, it is a fedup toy, not really unpopular. It was popular when it first launched but buyers will get fedup. LOL. Quote Link to comment Share on other sites More sharing options...

SRC Member reeftask Posted November 22, 2007 SRC Member Share Posted November 22, 2007 Its nice that you still likes what you bought. Many reefers buy and sell later after regrets. So must always survey before buy. Quote Link to comment Share on other sites More sharing options...
Gouldian Posted November 23, 2007 Share Posted November 23, 2007 strange not many pple contributing to this thread... think not a popular piece of toy. Hi bro, IMHO The key to a successful de-nitrator, be it sulphur or carbon base, is the dosing pump. This is because fluctuation will be detrimental to the anaerobic bacteria's populations. "All done, except for one last detail. A proper drip rate is needed to maintain dwell-time within the unit so the bacterias can gobble up the nitrates. Too fast a flow and your tests will show nitrites, as the bacterias have too much O-2 and denitrification isn't taking place. Too slow a drip or flow rate and hydrogen sulfides are produced, giving a rotten-egg smell that indicates trouble to the inhabitants of the reef or fish tank. I have experimented and found that a drip of just under a steady-stream is best. In other words, a very fast drip, but a definite drip just the same. Use a small air valve to regulate this on the output tube before running back to your sump or display tank." Source: http://saltaquarium.about.com/od/proteinfi...ycoildenitr.htm For me, I used the Aqua Medic NR1000, a carbon based Denitrator. In my 3 years of usage, I have to change my peristatic pump 5 times due to mechanical failure (1 x Aqua Medic SP3000, 1 x Aquadoser 201 variable, 1x TOM Aqualifter, 2 x IKS LP180). I am now using Iwaki metering pump which in my opinion is the best option for accurate dosage and reliabilty.

Gouldian Posted November 23, 2007 Share Posted November 23, 2007 gouldian, do you think it will have problem if we were to tee off from a return pump instead of another dosing pump? Hi Blenny, Its been quite a while since I saw your posts, guess you were busy. I have tried tee off before but find that its very difficult to maintain a consistent flow due to the fact that water will flow which ever way that have lesser back pressure. Thus if pressure of the other route is much lower than the one going into the denitrator, the flow may stopped totally one day. Just my 2 cents.

Gouldian Posted November 23, 2007 Share Posted November 23, 2007 has been quite busy for a while....looking for a new job. am looking into purchasing 1 unit of sulphur denitrator, any recommendations Oic. Not sure about sulphur based Denitrator. But personal choice will be German made ones. Quote "Reefs, like forests, will only be protected in long term if they are appreciated" Dr. J.E.N.

SRC Member reeftask Posted November 24, 2007 SRC Member Share Posted November 24, 2007 nowadays, kids toys are more expensive. They have computers and no longer play cheap toys, LOL. Their compouter are not the cheapo type but very high ends. Quote Link to comment Share on other sites More sharing options...
SRC Member zipp86 Posted November 25, 2007 SRC Member Share Posted November 25, 2007 just a question, why must we use dosing pumps again? i run a sulphur denitrator, feeding it with an atman pump, at the output i just control the dripping.. anything wrong with the set up.. only problem i have is air tends to build up in the reactor.. i dunno why.... hmmmm Quote Link to comment Share on other sites More sharing options...

Gouldian Posted November 26, 2007 Share Posted November 26, 2007 i believe you are an aquamedic fan Not really bro. Just happens to get that at a good price when a bro who bought decides to quit even before set-up. Quote "Reefs, like forests, will only be protected in long term if they are appreciated" Dr. J.E.N.
