    Reading about JBL Denitrol, it says to dose daily for 9 days, am I correct? Seachem Stability, what we have here, is dosed in the same manner but for 7 days. And then fish are added to the tank. What scares me are those test number, tho. If the numbers can be believed as valid and not just skewed from the Denitrol.

    In addition to what was said above, is it possible for you to get some media or gravel from a healthy established tank? This would speed up the cycling process considerably

    Thank you, I really appreciate the help.

    I do not think I am adding any Ammonia either. I was going to introduce Tetras after 48 hours of starting with Denitrol but because Ammonia was already high I haven't put any fish in the tank.

    Yes, Denitrol says the following:
    For newly established aquariums
    1st Day: 10ml for 100l (so I used 40ml)
    9 further days: 10ml for 300l (i'm using 15ml)

    I have no idea but could the ADA Amazonia cause Ammonia? Apart from that I have only put in plants and used JBL Biotopol to Dechlor the tap water.

    Our water is normally around pH 7.8. I have not tested it further but know it must be soft water as our kettle is very old and has never developed any limescale. Is there something I could do to test? I have the full JBL Freshwater Test Lab.

    So with the mystery Ammonia and low pH i'm really confused.

    Sadly I don't know anyone with an aquarium, and the stores will not give out seeded filters etc.

    If I remember correctly, the ADA Amazonia is a type of soil ?

    If yes, and it is not covered by a layer of aquarium subtrate, then that could be were you are getting ammonia from

    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    You can not cycle a tank with just a bacteria booster. You need a source of ammonia from something. Also, bacteria boosters can skew with test results, as well, sometimes so I would even be worrying about the pH for now. Especially when it's good right from the tap.

    I also am not familar with the products you are using so rather am in the dark here. Sorry.
    I mirror this post. Where is the ammo coming from? Yes ammo will cause the ph to drop. In the beginning of a new tank notning stays stable. It will take 6 months before things come to an even keel and you like what you see. Check your tapwater for ammo,do not add any fish till these things happen. ammo rises to 4,trites start showing up then ammo falls,trites will climb like crazy to God only knows what for a few days as ammo goes to zero,trates start climbing as trites fall to zero over another week or so,ammo and trite are at zero and trates are God only knows what,water changes bring trates to less then 20,add your first few fish. Once all these things happen and you are doing all you need to do for maint then the tank water ph will stabilize to somehwhere around a few points lower then the tapwater.

    Oh this!

    Cliff hit on it with the ADA apparently. I would not top it off because I think the spike will still be there but at least this does explain the danged ammonia coming from this unknown source.

    And another one

    ADA also lowers the pH. I have been reading power sand is used under it but can't find anything about topping it off.

    Sounds to me as you simply have to wait for that ammonia to process.

    Hi all,

    Thank you very much. So is this good news? Can I try and use this ammonia for the fishless cycle?

    Tonight i've done a 30% water change. After 2 hours the values are as follows:

    Tap Water pH : 7.6
    Tank Water pH : 6.8
    Tank NH4 : 3.0

    I'm going to forget the Denitrol for now.

    Shall I continue to test every 2 to 3 days and do water changes if the Ammonia goes above 5.0 OR the pH drops to 6.0?

    Thanks again for your time and help.

    I would suggest testing every day, just to make sure

    Looks like that substrate could provide you with the steady supply of ammonia that you need.

    I'm not sure I can call it cycling, as i've not been adding anything to the tank over the last 4 weeks, but I have been monitoring what has been happening.

    The source of Ammonia was leaked from the ADA Amazonia substrate.

    I've uploaded my values here:

    Please note the water changes were performed in order to keep the pH above 6.0. I've seen on here that pH values below this can cause cycling to stall or stop.

    What are your thoughts? I am concerned that my Nitrates have not really gone up. I am also worried that I have no control over the Ammonia and have no idea if the substrate is still producing / leaking it.

    I will continue to monitor the tank parameters.
