great question... I just got into testing myself. and would like to know more.

but u should probably post this under the chemistry and equipment forum.

I found the aquarium pharmaceuticals tests to be fairly easy... all u do is fill a tube w/ water then put in a few drops of solution. a pH test kit cost me ~ $5 and says it's good for 250 tests. it came w/ an easy to identify (laminated -smart) color chart to compare my results although it only reads from 6.0 to 7.6.

what kind of test kit did you get, it sounds simular to mine,

the ammonia is the confusing one to test in my kit, it has lots of steps and proceses that I don't understand?

I have the same one you do, loveforfish. I've tried a lot of test kits and that is my favourite. I'd agree that the instructions are just south of vague though.
Here's what I do for ammonia...
First I fill one of the test tube thingys with 5 ml of water- I use the included little tube that looks like a syringe to get it fairly exact. Then, I add 14 drops of the big bottle (labeled 1), put the cap on and swirl it around, then add 7 drops of the little bottle labeled 2. Then I put the cap on, swirl it around again, and add 7 drops of the little bottle labeled 3. Then I cap it up and put it aside for about 15 minutes. Then I compare it to the chart, and hopefully it's yellow! Red=bad.

I never noticed this until the lady at the lfs pointed it out, (I wouldn't) but you always use 14 drops when it's a large bottle and 7 when it's a small bottle. The only exceptions are the GH and KH tests, because with them you just add till it changes colour... You know the drill.
Hope this helps...

I also use the same test kit loveforfish and I find it very handy. I don't trust the dipstick kind of test because those strips can become contaminated very easily and end up giving bad results.

I know the dropper tests take longer but I think they're better at giving a more accurate result.

the nitrite test card is the NO2 one. the one that ranges from yellow to red.

hope that helps!

I'd give you my e-mail, but I actually don't check it a lot. It gets a lot of spam... Sad
You can pm me by pushing the little pm button underneath my message and I will probably answer you a lot faster!

[EDIT: to add the following]
I have four cards too.
One is for freshwater pH, that one ranges from a light yellow to purple. One is for saltwater pH, that ranges from a goldenrod yellow to dark purple. One is for ammonia (NH3/NH4), that ranges from a spring green to turquoise. The last is for nitrite (NO2), that ranges from yellow to red. This test kit doesn't test for Nitrate, but really as long as you do regular water changes nitrate shouldn't be an issue. It isn't toxic but in sizable amounts or over a long period of time.

thanks,

I mesured my amonnia and nitrite,

amonnia 0 mg/l

nitrite <0.3 mg/l

my tank has been cycleing for about 27 hours now with those test readings.

is it important to mesure GH or KH through the cycle process?
