Salifert Aquarium Test Kits
- KH / Alkalinity Aquarium Test Kit by Salifert : The Salifert KH/Alk aquarium test kit is very straightforward. It measures in sufficient small steps of 0.1 meq/L or 0.3 dKH with a sharp color change.
- Magnesium Aquarium Test Kit by Salifert : The Salifert magnesium test is very simple to use and does not suffer from calcium and strontium interferences when within certain bounds.
- Nitrate Aquarium Test Kit by Salifert : The Salifert nitrate test does not suffer from an amine interference. The very special ingredients allow a very fast and precise measurement.
- Nitrite Aquarium Test Kit by Salifert : Salifert Nitrite aquarium test kit probably is the most sensitive, accurate and fastest nitrite test kit available.
- Organics Aquarium Test Kit by Salifert : Measures most of the refractory organic compounds.
- pH Aquarium Test Kit by Salifert : The Salifert pH test kit is sufficiently accurate to monitor pH fluctuations of approx 0.2 pH units. Our KH + pH Buffer allows fast and efficient correction of alkalinity.
- Phosphate Aquarium Test Kit by Salifert : 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.
- Silicate Aquarium Test Kit by Salifert : Salifert offers a very sensitive and accurate silicate test kit. Silicate content can be decreased by using the granular Phosphate-Killer or the liquid Phosphate-Eliminator. Although both are designed for phosphate removal they have also a very high affinity for silicate.
- Strontium Aquarium Test Kit by Salifert : The Salifert strontium test kit detects both ionically free and moderately complexed strontium. Salifert was the first to introduce a strontium test kit.
- Ammonia Aquarium Test Kit by Salifert : The Salifert Ammonia test is very straightforward and measures the sum of toxic ammonia and ammonium in just a few minutes.
- Boron Aquarium Test Kit by Salifert : The Salifert Boron Profi-Test kit measures the level of naturally occurring boron in steps of 0.5 mg/L.
- Calcium Aquarium Test Kit by Salifert : Salifert is the only one in offering a true accuracy and precision as claimed.
- Copper Aquarium Test Kit by Salifert : The Salifert test kit offers a very sensitive and accurate test for measuring dissolved or weakly chelated copper from 0.05mg/L to 2mg/L.
- Iodine Aquarium Test Kit by Salifert : The Salifert Iodine Profi Test measures all naturally occurring iodine species such as iodate, iodide, molecular iodine and hypoiodite. No other test kit offers this possibility.

Seachem Aquarium Test Kits
- Marine Basic Multi-Test Kit 75 Tests, by Seachem : This kit combines the Marine pH & Alkalinity, Ammonia and Nitrite & Nitrate kits into one kit. (pH, alkalinity, free/total ammonia, nitrite, nitrate Multi Test Kit)
- Reef Special Multi-Test Kit 75 Tests, by Seachem : This kit combines the Phosphate, Silicate, and Iodine/Iodide kits into one kit. (phosphate, silicate, iodide Multi Test Kit)
- Ammonia Alert Sensor by Seachem : Suction cup the ammonia alert into your fresh or saltwater aquarium and read the color dot to determine the ammonia level at any time

Fritz Aquarium Test Kits
- Ammonia Aquarium Water Test Kit, 100 tests by Fritz : All Fritz freshwater Test Kits come with lab-grade liquid reagents for the most accurate testing possible. Easy to follow instructions and easy-to-read color charts.
- Nitrite Aquarium Water Test Kit 200 tests by Fritz : Nitrite Test Kit (Range: 0-2) 200 Tests
- pH Aquarium Water Test Kit, 250 tests, by Fritz : pH Test Kit (Range: 6.0-7.8), 250 Tests

Red Sea Aquarium Test Kits
- Red Sea Fresh Lab : Red Sea Fresh Lab measures: pH High, pH Low, Ammonia, Nitrite.
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 Plant Lab : Red Sea Plant Lab measures: CO2 & Iron. These are 2 Essential Tests for Planted Aquariums.
Carbon dioxide is the most important plant nutrient and is sufficiently and constantly supplied in natural waters by nutrition springs. These natural sources of CO2 are missing in the aquarium and it is, therefore, prudent to check the CO2 contents regularly. A consistent CO2 level of 30-40 mg per litre is necessary for a healthy growth of all aquarium plants and at the same time absolutely safe - even beneficial - for the fish.

Aquarium Hydrometers & Refractometers
- Deep Six Hydrometer : The unique design of the Deep Six Hydrometer allows hobbyists to take water samples at six inches in depth without submerging their hands in the water, thus avoiding the possibility of contamination.
- Salinity Refractometer with ATC by Milwaukee Instruments : The MR series refractometers are precision optical instruments used for measuring aquarium water salinity.
They work using principle of light refraction through liquid. When passing light through a liquid the refracted angle will be shown on the scale determining the amount of salt in the water.
- Salinity Refractometer with ATC by AquaMedic : This high-quality refractometer reads in both salinity and specific gravity values that are temperature compensated and can be easily calibrated with a drop of freshwater.
