    How to really measure water conditions properly

    Hello...

    I recently acquired the API gH and kH Test Kit...

    Can I ask how do I actually read the readings? they use degrees which will be converted to ppm... for example, 0* - 3* (0-50ppm) (* = degrees).

    So, when we see the guides to keeping different species of shrimps, when I see gH, for example, 4 - 6, is this 4 - 6 in the form of ppm? or degrees?

    VERY confusing! Please guide!

    Re: How to really measure water conditions properly

    You are refering is the recommended range. They place as 0-3 (50ppm) right? See the conversion table.

    1 Drop - 1 dKH - 17.9ppm GH/KH
    2 Drop - 2 dKH - 35.8ppm GH/KH

    Example, you were told the GH recommended is between 3-8 or 50-140ppm, means using the test kit, the drops needed (so that it change colour) is between 3-8

    ohh.. So can I assume that once i dripped 3 - 8 drips of the solution into the water and if the color change, means the gH level in the water is 50 - 140ppm? Which means, if they say gH: 4 - 6, when I drip 4 - 6 drips of the solution into the water, the color of the water will change?

    In short yes. You tested and on the forth drop it change colour. Hence when someone ask you what's your GH, you say 4. The manual will tell you the colour change.

    I will recommend you using sera ones instead of api ones ( sera ones are probably easier to use and differentiate in the colours)
    Aspiring to be.

    One thing about deducing the colour from hardness tests I observed, is that it's easier to "convince yourself" what colour you are looking at, by looking down the tube (placed on a neutral-coloured surface, of course) from the top, i.e. the opening, in addition to from the sides.

    Funny thing is the first drop into the water, I can see a very very very very very light tint of yellow... not very obvious. second drop, just a little darker. So Can I conclude that the gH for my water is 2?

    I think that means your gH is 1... or that's what I gotten from replies in other threads and forums. Any experts can clarify? Thanks.

    Re: How to really measure water conditions properly

    Huh? You're talking about GH or Kh?

    Between the two Gh is easier to see. From orange to green.

    Kh is blue to bright yellow. From my own experience, For kh on first drop its difficult to see but if it turns straight yellowish, then its one. It'll increase when the tank stablise at least for me for my planted tank.

    It comes with an instruction. If you lost that, google "api gh instruction" the instruction is in pdf.

    Re: How to really measure water conditions properly

    I use API GH test kit, but there is no orange. The test kit is Green and drops into the test sample which is clear water colour. Is my test kit expired?

    Well... the test kit is supposed to turn the water from orange to green... do you mean when u drop the solution into the water, it turns into green straight? If so, it might mean the gH in your tank is very high. hahaha... But correct me if I am wrong.

    Shrugs. Not sure about expiry. To confirm, ask a friend to borrow theirs. Just to confirm or you bring your test kit over to their place and you can test both test kit.

    One drop and turns green means 17.9ppm. Is this a new tank? What is inside the tank?

    0-4 very soft. 4-8 soft. 8-12 medium hard. Depends on what fish you are keeping. Adjust accordingly.

    On the contrary, I think my Gh probably very low.
    First two drops it remains transparent. Third drop it turns Green. I am thinking it means Gh=3.
    I tried recommended method of using 10ml instead of 5ml. It turned Green on 4th drop. So Gh=2. But I like this method of doubling the test sample!

    Re: How to really measure water conditions properly

    Can't comment as I am unsure of its significant of testing it in that manner. Good initiative though.

    It's recommended that you take your test kit, say API. Go to a friends house and he uses Sera. Follow the exact instruction for each test and then compare. Is it the same or slight difference and then come to a conclusion. As I am not keeping anything expensive, I don't need to test my GH or to monitor it. I only did so during the first two months. The bottle is still 95% full since last year. The GH/KH when I started was at 2/1. Then 3/1 - 4/2 - 6/3 and it maintains there. Mine is a planted tank with DW.

    Maybe the test kit has expired. You can get say mineral water to test if after 1 or 2 drops the water turns orange. If it is working it should turn from orange to green when you drop more drops.
    I ever had a Tera GH test kit which the color remains at yello/green after dropping the first few drops when testing mineral water, so concluded it has expired.
