This a really useful product. I use it often to make sure my water is safe for my fish. It comes with a guide that tells you what is normal and what to do to get the water at the right level.

Pros: easy to use

Cons: ?

I have never used these before in my three years of keeping aquariums. I used them for the first time when I recieved my free sample, and I love them! They are so easy to use and seem to provide a fast, clear, and accurate reading. I recommend these to all people who keep aquariums.

Pros: Easy to use, fast reading

Cons: none

This is a very good product considering its very cheap. Its really easy to use it takes about 30 seconds to complete the test which I think is great because I hate Taking a long time with my Tanks Maintenance. if You don't believe me then try it yourself they have free samples.

Pros: very easy to use, Very accurate.

Cons: If you get moistur in the bottle the strips may not work.

I used a strip right away and found I have very hard water and my nitrate tested high. I'll do a 25% water change and test again. Good company that sent the samples, thank you.

Pros: works almost instantly

Cons: none

These are very nice if you want to know a ballpark of the makeup of your tank. They are very easy to use, and are easy to understand. They aren't very exact, and if you want to know the exact numbers I would still recomend using a master test kit with viles and chemicals.

Pros: Easy, very quick

Cons: not very exact
