Tetratest Aquarium test kits Nitrite, Nitrate, ammonia and 5 in 1 aquarium test strips Tetratest  Freshwater 5 in1 Test Strips The Tetratest 5 in 1 Test Strips are the fast and easy way to find out if your water quality is safe for your fish Good water quality is the key to healthy fish and trouble free fishkeeping. Traditional methods of testing the water can take time, and are not ideal for situations where time is limited, or when frequent testing is necessary (for example in newly established aquariums). The TetraTest 5 in 1 dip test offers a perfect solution, by testing for 5 essential water quality parameters in less than 60 seconds. Simply dip one strip into the water, and within a minute you will have readings for nitrite, pH, carbonate and total hardness, and nitrate   SHOWS AQUARIUM WATER QUALITY IN SECONDS With the Tetratest 5 in 1 Test Strips, you can determine 5 of the most important parameters of aquarium water in one quick and easy step. No complicated instructions No special equipment necessary Simply dip and see 5 results in seconds To ensure optimum water quality, weekly testing of your aquarium water is recommended Measures: pH  ( 6.4 to 8.4) GH (General Hardness) KH (Carbonate Hardness) Nitrite (NO2) Nitrate (NO3) Contents : 20 Test Strips ( and Instruction leaflet with important information and helpful tips about maintaining water quality) For Freshwater Only 5 in 1 test kit  £9.95   Tetra Laborett Reliable and accurate, the Laborett Testing Kit for freshwater and marine aquariums provides professional measurement of the most important aquarium water parameters: pH freshwater and pH saltwater, carbonate and general hardness, nitrite, ammonia and carbon dioxide. The Tetra Laborett Kit includes reagents, two test vials, a water withdrawal syringe, color scales and instruction booklets with recommendations and helpful hints.   £19.95 Test for PH, KH, GH, NO2, CO2   Tetratest Nitrite NO2 Nitrite (NO2-) results in aquarium water as the natural by-product of decomposition of ammonia due to beneficial biological filtration activity. Nitrite is toxic to fish life, and is further decomposed to nitrate, but interruptions or inefficiencies in filtration can lead to its accumulation. Nitrite concentrations as low as 1.6 mg per liter of water can adversely affect your fish, and in severe cases is fatal. Regular testing for nitrite will ensure optimum water quality and verify filter performance. The Tetratest Nitrite (NO2-) kit includes two 10-ml test reagents (#1 & #2), test vial, color scale, instructions and recommendations and 45 tests.   £6.95 Tetratest  Ammonia Ammonia (NH3) is a natural, toxic by-product of animal metabolism and the decomposition of animal and plant waste materials. Ammonia toxicity is highly dependent on aquarium pH as it is readily converted to the less-toxic ammonium ion (NH4+) as pH decreases. At pH levels above 7.0, increasing levels of toxic ammonia exist. At pH levels below 7.0, ammonia begins to exist mostly as ammonium ion. Levels of total ammonia (NH3 + NH4+) of only 0.25 mg per liter of water can be harmful to your fish and other aquarium inhabitants. The Tetratest® Total Ammonia kit was professionally developed to accurately determine the ammonia level in your aquarium water. To ensure optimum water quality, frequent testing is strongly recommended - even more frequently when your aquarium is first established. The kit contains on 6-ml test reagent #1, one 10-ml test reagent #2, one 17-ml test reagent #3, a test vial, color scale, instructions and recommendations and 25 tests. Notes: Tetratest Total Ammonia kit is safe and accurate to use with other chemical products that remove or reduce ammonia from the aquarium and which can cause interference with less-expensive single reagent test methods. £7.95   Tetratest  PH Different types of tropical fish will require different pH levels and as a result, it is important to keep a regular check. TetraTest will accurately determine the pH of your aquarium so it can be kept in the optimum conditions. PH Freshwater test £5.95 PH Marine test £5.95 Tetratest Nitrate NO3 Nitrate is the end product of biological filtration and the result of decomposition of nitrite. It can also be present in tap water supplies, especially in areas of high fertilizer run-off. Although virtually non-toxic to fish, nitrate is a key algae nutrient and high concentrations can interfere with osmoregulation (the process by which fish exchange salts and other chemicals through the gills with the outside environment). Nitrate can be more toxic and irritating to saltwater invertebrates and should be monitored more closely. Nitrate testing is also an indicator of general water quality and filter function; as biological filtration converts ammonia, to nitrite and finally to nitrate, other import chemical changes take place in the aquarium simultaneously such as loss of alkalinity (buffering capacity) or the accumulation of phosphate - thus nitrate testing can indicate possible imbalances in other areas without directly testing each one. £9.95   Tetratest 02 Oxygen test kit Oxygen is vital to the well-being and overall condition of fish, plants and filter bacteria. Water contains far less oxygen than air, and at times it can become limiting. It is important to check oxygen levels from time to time, particularly at warmer times of the year. The only way to check the oxygen level is with a TetraTest Oxygen test kit. £8.95
