Comes in a strong plastic case with a carry handle for perfect storage. 

Testing for pH 
The pH value denotes whether water is acidic, neutral or basic. If the water is too acidic or basic, this can quickly result in the death of fish. 

Testing for NO2 
Nitrite (NO2) is produced by useful bacteria during the decomposition of ammonia waste secreted by the fish. Nitrite can adversely affect the health of your fish, even when it is present in low concentrations. Nitrite is decomposed by bacteria in the filter into nitrate that is vitually harmless to your fish. 

Testing for NO3 
Nitrite (NO3) is produced by useful nitrifying bacteria in filters of aquariums or ponds during the decomposition of toxic waste (ammonia and nitrite). Nitrate is not toxic for the fish in your aquarium or pond but too high concentrations can inhibit reproduction and growth. 
Nitrate is a plant food. A higher level of nitrate will simulate potential plant growth. Therefore aquariums or ponds with high concentrations of nitrate often encounter problems with 'suspended algae' and 'gliding algae'. 

Testing for KH / TA (Total Alkalinity) 
The TA, also called carbonate hardness or temporary haedness is formed by binding of calcium with carbon dioxide. This binding is important for the buffering of the pH in the aquarium or pond. 

Testing for GH (General Hardness) 
The GH measures the total amount of minerals dissolved in water. All the dissolved minerals that determine the 'hardness' of the water are essential for the biological processes that occur in your aquarium or pond. If the hardness is too low, this inhibits these processes, and the pond will become stagnant.
