nitrite still high

[cruzeoc]

i have had my tank cycling now for 2 weeks with live sand live rock and extra water from my old tank usualy i would notice a nitrite drop by now but im still up in the reagon of .3 to .8 and it's sticking and 1 no of any good ideas i have algae growing in my sump not allot though but come on my nitrite should have shifted by now ??

Well my 75 gallon has also been cycling for 2 weeks and 3 days now and my nitrites are still up there also. My last tank was the same way. My Nitrites have dropped slightly over the weekend. I'm sure your tank will move through the cycle soon.... be patient!

Cycling is the build up of a variety of bacteria strains. From looking at your results it shows you have not built up enough niitrifing bacteria to convert nitrite to nitrates yet. Probable cause is that to much ammonia is still being processed. Are you cureing new LR in the tank?? what are your other parameters like

i dont have l/r in there yet i have live sand and the nitrites are still sat really high thinking about doing a 50% water change

[MikeS]

Do you have any livestock in the tank currently?

Dont do a water change yet. tell me what your ammonia and nitrate levels are??

sorry mike to late done it now im having a ponder about my dsb it is live sand my other tank has a livesand dsb but not as deep and thats wonderfull it's bed is 2" but my new tank has a 4" dsb ?? but after a 4 day water change of in total 75% of my tank and the nitrites are still up there thinking of tearing the tank down and starting again??

[MikeS]

If your tank is free of livestock, let the cycle run its course....

The DSB will take some time before it begins to reduce nitrate....

I'm with Mike let the cycle run it's course. Also are you not going to add any LR to the tank? If you are be warned that you should experience another cycle when you do add the LR.

i have volcano rock plus a couple of lumps of live rock to seed the rock and live sand

[gman0526]

From what I have heard volcanic rock can release some metals into the water that are not advisable. I would trytry to get some base rock (dirt cheap) like the one from http://www.hirocks.com .


I don't know if this has any relation to the nitrates readings you're experiencing but just some food for thought. Maybe somebody else can clarify this for us.

rite it is called volcanic rock but it is man made and is element free i did check with my lfs but i did do a test today and it has dropped a tiny little weeney small bit so small hardly noticable
