SRC Member qwertman321 Posted December 7, 2009 SRC Member Share Posted December 7, 2009 Hello . Juz wanna post some pictures of my tank. My tank has been cycling for 1 week for now. Place a Small Cube of market prawn during start of cycling too. Tested at day 3 > nitrite 0.5ppm Tested at day 7 > nitrite 0.0ppm How come my nitrite go down to 0 so fast? Do i still nid to put food for the bacteria to survive? Nitrate 70 ppm If i juz let my tank cycle would it go down to 0? Quote Link to comment Share on other sites More sharing options...

SRC Member pokmingsheng Posted December 7, 2009 SRC Member Share Posted December 7, 2009 like the intense colour of the sand bed.. are you by any chance 1000litres as well?

jackywongto Posted December 7, 2009 Share Posted December 7, 2009 Can u guys explain to me why i have strange nitrite results? my guess is that the live sand helped? Are you using cured rocks from reefers/ your dad too?

SRC Member raydiative Posted December 7, 2009 SRC Member Share Posted December 7, 2009 Can u guys explain to me why i have strange nitrite results? IMHO.. if you're not too sure what may contribute to the wierd result.. best allow your tank to cycle longer... at the same time you can plan on your corals and LS... =] Quote A man with a reef tank is a man with an empty wallet...

Senior Reefer yikai Posted December 7, 2009 Senior Reefer Share Posted December 7, 2009 the NO3 will not go down. at this stage you will not have any anaerobic bacteria to convert NO3 to N2. even in most established system, this is very rare. unless u employ a DSB Quote Link to comment Share on other sites More sharing options...
SRC Member qwertman321 Posted December 7, 2009 Author SRC Member Share Posted December 7, 2009 Deep Sand Bed? Can u Enlighten me on how DSB work? Quote Link to comment Share on other sites More sharing options...
stewpid Posted December 7, 2009 Share Posted December 7, 2009 Love the way you hide your wavemaker! I think DSB should be explained by the pros here ba...but the rough idea i think is...if your sandbed is deep enough,there will not be oxygen/air at the deeper parts...which causes certain bacteria to grow which converts the NO3 to N2.....i think....(lousy explanation..zzz) Quote Link to comment Share on other sites More sharing options...

There are some species of bacteria (pseudomonas, bacillus etc) that are strictly aerophobic, meaning they cannot live in areas where there is oxygen content. oxygen is toxic to these bacteria and they will die if exposed to oxygen. in fact, pure oxygen is a very toxic gas. If we breathe in pure oxygen at elevated partial pressures, we will die too. anyway, these bacteria live deep within liverocks or in this case, a deep sand bed because there is no oxygen in there. these bacteria utilise an enzyme called nitrase reductase, that convert NO3 (nitrate) into N2 gas and water. 2NO3- + 10e- + 12H+-> N2 + 6H2O (this is the equation) hope this gives you a better understanding on anaerobic denitrification. the process is actually alot more complex.

SRC Member qwertman321 Posted December 7, 2009 Author SRC Member Share Posted December 7, 2009 Hmm i get it now, but i have another qns, if we have a DSB that no oxygen can reach , so how does the water pass through and convert no3 to n?

Senior Reefer yikai Posted December 7, 2009 Senior Reefer Share Posted December 7, 2009 good question. how then does the water reach inside? im not too sure too. the bacteria is the one denitrifying. not the water itself. substances can diffuse in and out of the sand bed without problems. perhaps that is how the bacteria reaches the NO3. strong flow is good for a tank with DSB too. you don't need a DSB since ur tank is so small. it will be ugly and you just don't need it. personally i have never tried DSB, but would like to in the future.

SRC Member qwertman321 Posted December 7, 2009 Author SRC Member Share Posted December 7, 2009 but if i dun make i DSB how can i maintain nitrate to be zero? other than changing water and using denitrater. Quote Link to comment Share on other sites More sharing options...
jackywongto Posted December 7, 2009 Share Posted December 7, 2009 Yup i m using cured Rocks from my dad but not live sand. I thought the sand are black argonite sand/ volcanic sand which are live?

Senior Reefer yikai Posted December 7, 2009 Senior Reefer Share Posted December 7, 2009 but if i dun make i DSB how can i maintain nitrate to be zero? other than changing water and using denitrater. ur NO3 is now 70 because it is still cycling..... do a final water change after cycling is complete. maintain ur NO3 with low stocking and light feeding. water changes etc. you have much to learn and read up on. with good cycling and tank maturation, NO3 should not be much of a problem.
