Ammonia is extremely toxic to aquatic life, even in quantities as small as 0.5ppm, yet it is a very common substance. It is produced each time something organic, like fish waste or...

High calcium levels. Too much calcium in the water results in reduction of carbonate hardness levels and fluctuating pH. Normal seawater contains 350-450ppm calcium. Please refer to a good reference for each freshwater...

Carbon Dioxide (CO2) is present in water as a dissolved gas, like oxygen. High CO2 can stress and even kill fish. It also forms carbonic acid, which lowers the pH. For freshwater...

A Carbonate Hardness test is a test of the carbonate and bicarbonate extent contained in a sample of water. It affects all aquarium's both salt and fresh water. It is called many...

As a treatment for marine parasites, copper based medications are still the most effective and least harmful to marine fish. However specific levels of copper are important to obtain a successful treatment of...

The hardness of water can be just as critical to the well being of an aquarium as pH. In fact with many fish it can mean the differnece between good health and...

This kit determines iron down to a level of 0.25ppm. Correct levels of iron are essential for the growth of aquatic plants, but too much iron could harm both fish and plants....

Nitrate is toxic to fish at high levels and is extremely toxic to some invertebrates even at low levels, so specific tolerance levels need to be determined. Nitrate is also a major...

*Approx 85 tests *1- 5ppm - 10-20ppm *Fresh & Salt water

Probably the best fresh water pH test on the market with more tests (approx 150 per kit) and more accuracy due to the unique way the result is determined. Namely more test...

Ideal for Cichlids and fish preferring high pH values. - Measures pH from 7.5 to 8.4. - Easy to use, immediate results. *Approx 25 tests *PH 7.5 - 8.4 *Fresh & Salt water

The indicator used in pH MARINE is unique. It is a mixed indicator with an ideal range 7.5 to 8.7. Determinations can be made even without a colour chart. Yellow is too...

Phosphate is a very important parameter in fresh and salt water aquaria. High phosphate levels are often quilty of causing ulgy algae blooms in all aquarium types. Incidentally, this can be rctified...

AZOO Trace Element TEST For aquatic plant aquariums and ponds Aquatic plants, invertebrates and fish require trace elements to proceed with metabolism and growth. These trace elements will decrease during the metabolism process or...
