  1. Default Using Ammonia for fishless cycle


    0 Not allowed!
    I've been reading about doing a fishless cycle with Ammonia and that's probably what I'll end up doing.

    Can anyone tell me, loosely, how much ammonia to add to a 75 gallon tank. I know that the amounts vary and the general reading should be 4-5ppm, I just need to know a quantity to start with.

    Dose a bit, wait 15 minutes, test. If you need a tad more, then add a tad more.

    +1 - don't put in too much at a time - if you end up putting in too much you'll need to remove some - too much can stall the cycling process.

    5 gal QT with green corys & 2 guppies

    Ok, but what are some common amounts added to a 75 gallon tank?

    5 drops per gallon? 1 drop per tank? 17 buckets per gallon?

    Just in general. How much did you use for your tank and how big was your tank? I just want a general idea.

    I did this. Dosed a bit, waited 15 minutes, tested.

    There is no exact measurements because all ammonia is not the same percent.

    There have been people who kept very close track of how much they put in so they knew 15 drops, or a capful, or 1/2 teaspoon got their tank up to whatever reading they wanted - so, like LH said, if you find that 5 drops (or a half teaspoon for that matter) doesn't register any ammonia, then add another 5 drops or another half teaspoon...repeat if necessary!

    It doesn't work like that because it's not a recipe [As mentioned, There are too many variables], The typical route is this:

    You dose. You then determine what level you have reached by testing and you then redose as required until you reach your target dosage.
    Gas mileage isn't everything OIIIIIIIO
    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.

    When I did my 55 gallon I used the Ace brand ammonia. It believe it was 10% strength.

    I dosed 5ml (used a test tube from API test kit as measuring device) and it brought ammonia up to around 5ppm.

    Here is a calculator I found online. It worked well for me.

    This thread is a great example of why you can not always trust the on-line calculators to tell you how much ammonia to add to your tank. Johndimo used 5 ml of a 10% solution to get around 5ppm of ammonia in his 55 gallon tank while the above link tells you that a 5 ml amount of 10% ammonia will give you 9ppm in a 55 gallon tank.

    While those calculators may be somewhat accurate at times, I have never found them to be reliable. There are far to may variables that pop up for those calculators to be accurate in all conditions. I've tried a few different ones as well.

    The best is approach is to add a bit, wait, test, and re dose as required. That had always worked best for me

    Just my $0.02

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