    So my new system has been running for six months now. Running on Zeo and its been lets just say interesting.

    One thing I can't seem to shake is nitrite for what ever reason its still present in my system.

    I watched the nitrate and phosphate come down to:
    N03: 0.50ppm
    P04:0.03ppm

    But the dam Nitrite is always hovering around 0.25, 0.5ppm. I checked the ammonia levels - 0ppm.

    The system is well settled now, getting serious growth in SPS and LPS. Fish are all happy as pigs, fat and bullish as usual. Skimmer (Vertex Alpha 170) is skimming like a machine, Zeo doing its thing.

    I do about 100l water change every week (for now), tested the water that I am changing with N02, N03, P04 all = 0ppm - Moving to auto water changes daily once I know my travels are finished and I am going to be in town for a while.

    I am just not sure where to look for anymore, what to remove or what to do. I want to get to 0 nitrite but it's just sitting there doing its thing between 0.25 and 0.50ppm

    Any ideas?

    So I thought about that and did the following:

    Bought and tested with:
    1. DD H2Ocean
    2. Salifet
    3. Red Sea - high accuracy

    All give me the same result.

    Took it to @bryan we did the same tests and got the same result for the Nitrite.

    well i would go with bad test kit, or not enough filtering capacity for your lifestock

    if ammonia is zero and you have nitrite and no nitrate i would go with a bad testkit
    if you had nitrite and nitrate then i would say not enough filtering. while you are running zeovit, its benefit is for corals, what is your fish stocking levels?

    Fish stocking levels I would say is medium I have about 20 fish, 4 of which is medium, 100l water change a week is more than 20% and with the Vertex Alpha 170 skimmer, feeding ONCE a day flakes - you still think its stocking levels? You saw the stocking levels nothing has changed since then.

    No ammonia.

    Tested about 20 times - 15 times first as I thought the test kits were wacked so went and got three different ones did 5 x 3 test kits - same result.

    Took it to the LFS same results !

    I will do morning and night tests and see what it does.

    I watched the nitrates and phos come down to close to nothing but nitrite stays the same in that range. Its highly frustrating ....

    Try dosing a new/other bacterial strain, perhaps your cycle is locked on the nitrite to nitrate leg, weird?

    Strange,
    Couple thngs you can try;
    1. Clean Skimmer more Frequently,
    2. Check for Dead spots in the tank, check for Detritus
    2. Have a sniff at the live rock, if it smells fowl that's where the problem may be,
    3. Try stopping the suppliments for a couple days see if that improves anything.

    Nitites and Nitrates normally diffuse downward into either anaerobic regions within the Live Rock or anaerobis layers within the DSB, somewhere there seems to be a shortfall.

    have u recently added the Live Rock or anything new? Or was it sorted as the tank cycled, for some reason it sounds as tho the tank is doing another cycle. Would this be true in any way at all?
