ask as many questions as you like, that's what the forum is all about, believe me, nobody will get fed up with answering questions.
Not familiar with those test kits, package and does look similar to Hagan though.
Okay, I'm sure everybody will have their opinion on test kits. The only tests I carry out are Ammonia, nitrite, nitrates and pH. I don't bother checking the hardness or chlorine, I know there's no chlorine because I use a water conditioner, I'm certainly not going to waste my money on a test kit. As for hardness, I personally don't bother with it, nothing wrong with checking it, however, you do have to have quite an understanding of what to do if you want to try and change the water. I certainly wouldn't recommend messing around with water unless you know what you are doing.
You should get quite a lot of tests out of one kit. Personally, I have been using the aquarium pharmaceuticals in the last few years, very good value for money and very easy to use
