Tetra Test 6in1 25 Strips

– Fast and easy testing of water quality
– Dip test for checking 6 water quality indicators in just 60 seconds
– Measures pH, Carbonate (KH), General Hardness (GH), Nitrite (NO2), Nitrate (NO3) and Chlorine (Cl2)
– pH – the pH value describes the acidity or alkalinity of the water, which is very important

for healthy fish. A value between 6.5 and 8.5 is ideal – KH – the bicarbonate hardness ensures a stable pH value.

Values between 3° and 10° dH are generally recommended
– GH – the general hardness has a direct influence on of the health of fish, plants and

micro-organisms. A value between 6° and 16° dH is ideal

– NO2 – a nitrite level of nearly zero shows that the filter is working properly and the water is safe for fish
– NO3 – the nitrate content shows how ’fresh’ the water is, and also how likely it is to support algae growth

– Cl2 – provides information about the water’s chlorine content. A value which is too high is harmful for useful bacteria and fish
