Fast, easy and accurate. over 550 tests API Saltwater marine master test kit  £24.99   API Reef Master Test Kit   To maintain and grow healthy corals, the correct balance of calcium and carbonates is essential, as are low levels of phosphate and nitrate.  This kit provides highly accurate testing for each of these critical parameters:  calcium, KH, phosphate and nitrate.  Unique, transparent dome allows clear view of contents.  Kit includes computer-calibrated and laminated colour cards, 4 glass test tubes and holding tray.  Also contains complete, step-by-step instruction booklet, including information on how to correct unsafe water conditions.  Compact to store. API Reef master test kit  £26.99     TMC Salifert Ammonia Test Kit Ammonia and ammonium are substances which should be converted rapidly into nitrite followed by nitrate and nitrogen gas. If this does not happen then the aquarium is not fully cycled or biological processes are not proceeding as they should. The Salifert Ammonia test is very straightforward and measures the sum of toxic ammonia and ammonium in just a few minutes. The kit can perform approx. 50 measurements and can detect 0.5 ppm of total ammonia easily TMC Ammonia 50 test  £8.99   TMC Salifert Calcium Test Kit TMC calcium test is capable in resolving the calcium content in 10 mg/L steps. The colour change is sharp and facilitates the detection of small but highly significant fluctuations in the calcium concentration. Salifert is the only one in offering a true accuracy and precision as claimed. The kit can perform approx. 50 - 100 measurements. TMC Calcium 50 - 100 test  £11.99   TMC Salifert KH / Alkalinity Test Kit The Salifert KH/Alk test is very straightforward. It measures in sufficient small steps of 0.1 meq/L or 0.3 dKH with a sharp color This makes detection of important yet small change possible. The kit can perform approx. 100 - 200 measurements TMC KH test kit  £7.49   TMC Salifert Magnesium Test Kit The Salifert magnesium test is very straightforward and does not suffer from calcium and strontium interferences when within certain bounds. It measures in sufficient accurate steps of 30 mg/L with a sharp color change. The kit can perform approx. 50 measurements. TMC Magnesium test kit  £13.49   TMC Salifert Nitrate Test Kit Many nitrate test kits are prone to amine interference. This can give results much lower than actual. The Salifert nitrate test does not suffer from such an amine interference. The very special ingredients allow a very fast and precise measurement. The range spans from very low to a very high nitrate concentration (approx. 0.05 20 mg/L as Nitrate-Nitrogen or 0.2 100 mg/L as nitrate ion). The kit can perform approx. 100 - 200 test TMC Nitrate test kit  £10.49   TMC Salifert Nitrite Test Kit Many nitrite test kits have the potency to suffer from amine interference resulting in toxic nitrite not being detected. Salifert’s Nitrite test kit does not suffer from such an amine interference because very special ingredients are used. These same ingredients also result in a full color development within minutes. The developed color is very intense making detection of even minute traces of nitrite easy. It probably is the most sensitive, accurate and fastest nitrite test kit available. The kit can perform approx. 60 measurements TMC Nitrite test kit  £7.49   TMC Salifert Strontium Test Kit Strontium plays an important role by accelerating coral and calcareous algae growth. Since the growth of corals and calcareous algae goes hand in hand with strontium and calcium depletion, depletion of calcium usually means depletion of strontium as well. It is advisable to maintain a strontium concentration between 5 and 20 mg/L. Approx. 25 tests per kit. Measures in approx. 5 ppm increments. TMC Strontium test kit  £19.49   TMC Salifert Phosphate Test Kit Since phosphate can have major consequences when present in a concentration above 0.05 mg/L a test kit should be able in detecting even lower concentrations. The Salifert phosphate test already detects, within seconds, 0.015 mg/L of phosphate. This makes phosphate measurement highly reliable and informative allowing timely measures to be taken. The kit can perform approx. 50 measurements. TMC Phosphate test kit  £9.49   Red Sea Reef lab Ideal for saltwater reef aquarium systems. Tests for nitrate, phosphate and calcium with enough reagents for 60 tests each. The kit also includes 6 reef supplements: calcium, strontium, molybdenum, iodine, trace elements and vitamins.     Reef Lab  mini £45.50   Red Sea Marine lab Correct water conditions are essential for the health and development of both fish and plants. A stable pH maintained at the natural level for specific aquarium inhabitants, is essential for their well being and therefore should be checked regularly. Red Sea's Test Labs come in a unique package that easily transforms into a user-friendly workstation. The wide colour graduations of the tests have been developed for easy determination of the result       Marine Lab  mini  £45.50   pH & Alkalinity 100 pH / 60 alkalinity tests. Nitrite 80 tests Ammonia 45 tests Nitrate 60 Tests       Red Sea - PH/Alkalinity 100 pH test  / 60 alkalinity tests- Easy to use tests for marine and freshwater aquaria measuring pH values from 7.4-8.6. Alkalinity test accurately measures buffering capacity in marine aquariums.     Red Sea PH Alkalinity Test   £15.99       Red Sea  - Ammonia 45 tests - Measures total ammonia in both marine and freshwater aquariums. Test includes easy to read colour card and conversion scale to calculate level of toxic NH3 , NH4 and ammonia.       Red Sea Ammonia test Kit  £12.99  Marine or Freshwater aquarium     Red Sea - NitrIte 80 tests- Easy to read colour scale. Detects 0.05 to 10 ppm of nitrite (NO2 - ion) in both marine and freshwater aquariums. Test daily in a new aquarium or when there is a suspicion of a malfunctioning biological filter     Red Sea Nitrite Test Kit £12.99 Marine or Freshwater aquarium       Red Sea - NitrAte 60 Tests - Detects very low levels of Nitrate from 2.5 to 100 ppm (NO3- ion)  in both marine and freshwater aquariums. Easy to real colour scale greatly improves accuracy.  Test weekly.     Red Sea Nitrate Test Kit £15.99  Marine or Freshwater aquarium     Red Sea  - Calcium Pro 25 tests- Simple to use 2-step titration test good for the measurement of dissolved calcium accurate to 10 ppm.     Red Sea Calcium Pro Test Kit £13.99       Sera  - Phosphates PO4   For approx. 40 measurements. Phosphate strongly promotes algae growth. Thus, it should be regularly checked by means of the sera phosphate-test and removed with sera phosvec. The phosphate level should be below 1 mg/l (fresh water) resp. 0.1 mg/l (salt water). In case of high phosphate levels we recommend planting more plants and carrying out water changes more frequently.     Sera Phosphates test kit  £15.99       Sera  - CA Calcium Test   Ornamental algae, corals and other invertebrates always require sufficient amounts of calcium to ensure healthy growth. Natural calcium in the ocean is about 410mg/l. Ideal calcium value in marine aquariums is between 400 and 450mg/l. Regular checking of calcium level in your aquarium is important. Sera calcium-Test (Ca) kit is fast, accurate and easy to use     Sera Calcium test kit  £13.49       Sera  - MG Magnesium Test   An optimal level of magnesium in a saltwater aquarium is required in order for invertebrates and ornamental algae to thrive. A perfect example is calcareous red algae. This ornamental algae requires a great deal of magnesium as they integrate this element into their skeleton. Just as in nature a saltwater aquarium should maintain a magnesium level of c. 1300mg/l (ppm). The sera magnesium-test allows you to determine the magnesium level in your aquarium quickly and easily.     Sera Magnesium  test kit  £29.49
