Since someone recommended this as a cheap and not bad test kit, I assume there should be people using the above products.
I have some queries regarding the KH test kit.
According to the directions for use..
" 3. Add Carbonate Hardness Test Solution, one drop at a time, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops. After first drop is added, solution will turn blue. If the water sample contains only 1°dKH, the solution will turn from clear to its yellow endpoint after the first drop is added. "
Can I confirm that there isn't any color reference card with the test kit? So for people who are using this test kit, does the solution really turn blue after the first drop? I am asking coz mine turn very pale yellow. So am I right to say, if you're using aquapharm KH test kit and suppose your KH is 4 degree, then what you should see is blue-blue-blue-yellow?
I already have my baking soda standing by.

there is no colour reference card.
what you are saying is correct.
if you did not add any baking soda or your tank does not have any carbonate buffer, you'll most likely get pale yellow after the first drop.
you can test by adding a little baking soda to a some water and dose a single drop of the kh tester.

I use the same kit. You are likely to have 1°dKH or less.
For more than 1°dKH, you should see blue colour first.

BC,
have you compared readings between ap and sera kh test kits?
would age of test kits play a part?
comparing results between my year old sera with my new ap kh test kit, I get 1dkh higher when ap test kit is used. so what your comments?

Thanks for the prompt replies. A follow up question.
I got my baking soda (not baking powder as cautioned) but it is labelled sodium bicarbonate potash, can I use that?
Also how should I go about adding the baking soda? Must I increase the KH gradually as in maybe add sodium bicarbonate solution every few hours or it doesn't matter, I can juz stir the 2.5 teaspoon of sodium bicarbonate into 1 tub of water and add one shot? Thanks for any advice.

check the faq section.

sorrie a abit off topic, does anyone knows where u can get AP nitrate test kits at the west. Try bukit batok liao, they dun have. Thanks
c328 has all the aquarium pharmaceuticals test kits
KH & GH
PH
Ammonia
NO2
NO3

I like them alot since they are only 1 or 2 liquid reagent only.
NO3 = 2 reagent, as compared to all the 4 x reagents required by most other brands.
Can anyone vouch for the accuracy of the NO2 and NO3 test kits by Aquarium Pharmaceuticals...?
thanks for the info.
just been to C328 today, no NO3 test kit. Then went to another shop n ask, the uncle said no stock. Anywhere else can get?
c328, you can ask the auntie if you don't see it. she may have in her storage area.. (which I did ask)
AP NO3 test kits can be found at...
Petmart, PianYiDaoXiao(Bedok North, Block 84)
not sure you meant the aquarium pharmceuticals brand since that's the only no3 test kit I know with only TWO liquid reagents.
does pian yi dao siao has AP No2 & PO4 test kit?
thanks
NO2 yes....hard to say, maybe when you reach there and it sold out how??
AP don't make PO4...please refer to their web site for details www.aquariumpharm.com
should have asked. maybe next time free then go again. seems like the west side very difficult to find. bedok too far. But i did saw AP NO2 test kit at C328, left 1.
ok, then what's is the recommedation for PO4 test kit?
JBL is expensive $20+
thanks
