Aren't they so relaxing and pleasing!
There are different kind of tests -like test strips and liquid tests. Both kinds are available indivisually and in test kits. THis is an example of a multi-test strip kind:

I put examples of the test kits becuase these are the water quality parameters most frequently tested - so it is often easier and more economical to but them altogether. Test strips are a little less accurate than liquid test kits - and depending on the type of water conditioner you use, you may require a liqiud test.
I like to keep both kinds on hand!
I see you read the cycling page - when you look at the graph on top showing how different chemicals surge and decrease as your water "cycles" - becomes established as an eco-enviroment - you can track the progress by using the test kits - as some of the phases contain chemicals toxic to fish!!! Like, ammonia. THeyre will be a big ammonia spike that can kill fish if not monitored - aka New Tank Syndrome - and NitrItes will also spike and harm the fish. So, it is important to know when to change the water to help protect the fish.
The filter you have is trying to establisha bacterial colony of "good bacteria" that will breakdown the toxins in the tank - ammonia and nitrIte - and convert them to breakdown products that are less harmful to fish - NitrAte. You knwo when your tank is established when you finally see a nitrAte reading insicating that the good bacteria are flourishing in sufficient quantity to keep the water healthy.
A LOT more can be said about water testing - and you can look in the water chemistry forum to find more - but hopefully this helped a little!
BTW - I find this little test very handy when cycling:
http://www.thatpetplace.com/Products/KW/se...1/Itemdy00.aspx It hangs in the tank and can be glanced at quickly to give the ammonia level (it is not perfect but it is a helpful tool).
PS - the fish may be a little scared - they are sensitive to sudden changes and such - like light - and they have had a stressful move! They may still be sdjusting. And they may be sensitive to the uncycled water... that is where the test kits come into play! (Sorry about my typing - I can spell, I can't type)!
