    I've got an api freshwater master test kit however I got no instructions as to how long to wait for each test. Can someone supply me with the times I have to wait after I put in the last drop of solution. Also can the solutions be halved for longer use and does this effect the times I have to wait.

    Regards Timber

    Hi Timber,

    Can read PH straight away, Ammonia, Nitrite and Nitrate wait 5 mins and take readings.

    Dont know if I'm correct but I half the quantities for Ammonia and Nitrate. Seems to work OK.

    Hello Timber,

    The pH test you read immediately, after you have inverted the vile about 10 times. The ammonia test, you dispense 8 drops from #1 cap it and invert 10 times, add 8 drips from #2 cap it and invert (shake) 10 times, and then read the results after 5 minutes. For nitrites you add 5 drops, cap and shake 10 times and read the results after 5 minutes. For nitrates you need to follow exactly: add 10 drops of #1, cap and shake 10 times...Then take the #2 bottle and shake it for at least 30 seconds, add 10 drops to the vile, and then shake the vile for 60 seconds, read the results after 5 minutes.

    Your second question, the answer is yes the solutions can be halfed, and the chemicals can be halved and the time would not change, but you have to be very precise about this. For instance you are not going to half 5 drops of nitrite solution or 3 drops of pH solution. I would strongly suggest you use the vials provided (5 mls) and fill them until the "curve" of the water touches the white line.

    Thanks man, got some plants in today and doing the fishless cycle thing. Elmore field days on next week but can't see any stands that sell fish. Will have to do some research on fish sellers in Victoria. Think I will go with S/Perch or Catfish.

    Hi Timber

    Wendy was spot on with her instructions, I would just add a few things
    My Ammonia #2 bottle has a crystalline deposits around the top, hence
    it's a very concentrated solution. I now make a habit of shaking the
    bottles before using.


    If you want your ammonia test to last longer you can halve the
    quantities that you use.

    I would go to your local chemist and get a 3ml to 5ml disposable syringe.

    You would then measure 2.5ml of fish tank water into the test tube,
    then add only 4 drops from each bottle.(ammonia)
    It actually works out better because you can take a glassful of water
    and then syringe out the required quantity. Your not fiddling with four
    tubes at once hence less likely to drop/break any.

    I'm getting my Silver perch from Livefish $45/25 fish delivered to your door
    That in my opinion is magic, I don't even have to get out of bed.

    The instructions are on the back of each colour card, and no, you cannot dilute the chemical, it will spoil the test.

    Thanks Trout that is exactly what I'm looking for.

    No offence Murray but I'm not blind yet, the kit came with one colour chart showing all the colours for the different tests and there are no time instructions anywhere in the kit, all there is is the drop amounts on the individual bottles.

    That is a mighty strange API test kit.....If you got it from me, send it back and I will give you a new one.

    There should be individual colour charts for each test...

    Freshwater Low Range pH
    Freshwater High Range pH
    Freshwater Ammonia
    Freshwater & Saltwater Nitrite
    Freshwater Nitrate

    And sometimes ...

    Saltwater Ammonia
    Saltwater Nitrate

    Sorry if I wasn't clear ...... if you are reducing the amount of reagent you use by half, then you would also have to reduce the volume of water you are testing by half (2.5 mls exactly) this way you are not diluting your test, you are just reducing the volume of the test.

    I purchaced this one off ebay, may have been a poor investment in hindsight.
    Tested water at 0900 this morning, bear in mind I have had water running through and sitting in the system for a couple of weeks now. Added plants yesterday and seasoled the water.
    Results are; Water temp 19
    Ph 6.6
    Amm 2
    Nitrite 5+
    Nitrate 5

    I might get a Ammonia test kit from Petstock and test against this ebay one, if I get different results I will get another test kit.
    I will test again this afternoon to see if results vary with temp.

    Regards Timber

    Timber this is what the colour charts should look like on both sides. Probably some cheap imitation on ebay or maybe just ran out of ink printing the backs of the clolour charts.

    Here are a couple of photos of instructions etc. If hard to read click on the photo and press ctrl + to enlarge (ctrl - to minimise)

    You will notice on the top of each bottle a lot number. The last 4 digits indicate the month and year produced. Does your bottles have this?

    That Nitrite reading is a concern if you're adding fish in the next few days... when are they arriving??

    Dates are on bottles earliest is 1109 latest is 0210.

    And roberetofoz I'm not putting any fish in until it all looks good. No rush to buy fish just to see them die.

    I do have a question, do I have to have the airator running yet as I am not. Will there be enough oxygen produced through water movement to produce the bacteria, and will that alter the tests.

    Looks like manufacturer has changed their packaging because your test kit is a lot later than mine. Maybe there should have been an instruction sheet included?

    If you run your air pump now it will speed up the cycling a huge amount, the nitrification process dose require a fair amount of available o2 in the water without the bacteria colony will struggle to reach a satisfactory size

    Well I'll be - they must have changed the packaging and forgot to issue instructions on those API Test kits!
    I agree with Daryl - hook up an aerator and get those bacteria pumping along. They need the oxygen to do their thing so don't scrimp on the air, its just defeating the whole purpose.

    Still could be a dodgy kit from some backward country but will turn on the air and test every day, should see some sort of change in the near future.
