How To Use An API KH Test Kit

Here's a short video about using an API KH test kit.

Take your number of drops and multiply it by 17.86 to give you a total ppm. This is how you can estimate how much carbonate is in your water.

Bro thank you so much cuz the instructions with the kit or mad confusing!

[LienNguyen-vqqv]

Very good and funny videos bring a great sense of entertainment!

Yes thank you my gh I was just adding a bunch never changed was super confused

[MikeMV]

If your GH is zero (no color change even after 40 drops), does this have any implications for planted tanks?

My tap water as well as my tank water comes back with the same results. Thanks.

Hey Dan.. So it took 6 drops in kH to turn yellow. Question : So that means it has a bit of stability ? Less likely to get pH swings ? Right !

My KH test solution is orange, but when I add it to water, it doesn't turn blue, it just stays orange. Add more drops, still orange. My GH test solution is already blue/green and never turns orange/yellow. Is my test solution just bad? I ordered the test kit from Amazon and several people are complaining of bad batches in the reviews.

i put 4 drops in; water finally changed to pale yellow. How much hardness is in my water?

[WogChilli]

2 drops KH, 14 drops GH, is this bad?
I might have to look at getting an RO filter or maybe rainwater.

Is my water fine if one drop changed to the right color? We are not understanding this

[MK_Aquatics]

So I did this to my rodi water, and the took 1 drop and gh took 1 drop. But my ph is around 7.6-7.8 why is that?

[anthonybeneventano]

i think my ponds ph and kh have crashed, on the first drop for my kh test the water turns light yellow any idea if this is a crash? the tests are new and ive done about 800 gallon water changes my pond is 2000 gallons

[metropk]

I had 10 drops and it turned greenish yellow should I dose kalk or thats good enough for sps corals?

[berniedomigan]

Hey Dan. I'm keeping African Cichlids which of course means my GH and KH are both between 9 and 18 degrees approx. Is it necessary to do the test 1 drop at a time or if I know my levels are higher than 12 can I just start with 10 drops and add 1 or 2 at a time after that ?

[freecuddles]

hi. my fish are fine. but ph 7.2. shall i do kh

[barbaravictor]

how much hardness should be in my water?

[george]

Are we supposed to add the number of drops from both tests, and then use total drops as the measurement? I ask because instructions included with the test kit are so ambiguous. (and fine print that is too small to read)

[barbaravictor]

How much hardness should water be for discus fish?

[TCgirl]

What I want to know is where I can get that nail polish.

[Spham]

Hi, the moment I put in the KH - the first drop turns my water to orange/yellow. Is this bad?
