Very convenient and everything available.

I've bought the test lab for my freshwater aquariums and can fully recommend you have everything inside what you should test from time to time or at behavioral changes in fish and could.
You can use it very well recognize what a behavioral change might be, or whether diseases may arise due to changes in water values, as it is used for occasional control.
The package includes not only all things to the water to test the no explanation why and what you should consider as you get everything around it the same in the enclosed table to capture.

Conclusion:

It is not a must as long as the aquarium works but it is a great help to the water values ​​to test quickly and easily as cheaper and faster than ever to run in the pet store. and it's all rather than united in a suitcase in many boxes.
I highly recommend it to make it the Fischis always goes well.
