Onyx Sand is a specially fracted, stable porous gravel for the natural planted aquarium. Being carbonate rich, Onyx Sand provides an advantage to any plants able to utilize bicarbonates. Although ideally suited to planted aquaria, it may be used in any aquarium environment. Onyx Sand is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Onyx Sand is not chemically coated or treated but does have a slight buffering capacity that may raise pH by 0.1 - 0.5 pH units (depending on source water characteristics).

Nutrafin's carbonate and general hardness test kit measures carbonate hardness (kh) and general hardness (gh) in fresh and saltwater aquariums. Carbonate hardness (kh) must be tested on a regular basis because it fluctuates over time and can negatively impact the ph balance of aquarium water. Low carbonate hardness will result in poor plant growth. Testing for general hardness (gh) should be done to determine if levels of calcium (ca) and magnesium (mg) are optimal for specific species of fish. The kit includes one 15-milliliter bottle of kh reagent, one 10-milliliter bottle of gh reagent, one glass test tube with cap, one pipette, one lab base, one instruction booklet. Measures 2-inch length by 5-1/2-inch width by 5-inch height.
The Nutrafin Iron Test Kit allows you to measure the iron level present in your aquarium. Iron levels need to be carefully monitored in order to maintain lush, planted aquariums. It is recommended to test iron with a frequency that will maintain the suggested iron level of 0.25 to 0.5 Mg/L. By using the Nutrafin Iron Test Kit you are able to help ensure a beautiful planted landscape in your aquarium.
The Nutrafin Phosphate Test Kit allows you to measure the phosphate level present in your aquarium. Phosphate levels should be monitored weekly. High levels of phosphate, often the result of overfeeding or infrequent water changes, can contribute to unsightly algae growth. Therefore, the phosphate levels should generally never exceed 1 Mg/L. The Nutrafin Phosphate Test Kit is the ideal way to monitor phosphate levels, ensuring your fish is provided with the most comfortable living environments.
The Nutrafin Nitrate Test Kit allows you to measure the nitrate level present in your aquarium. Nitrate should be tested on a regular basis as a measure of pollution in the aquarium and to determine if a water change is necessary. Nitrate accumulates in aquariums over a period of time and is difficult to remove by conventional filtration means.

This test kit features a unique dye that has a pronounced color change between 8.0 and 8.3, making it the easiest kit on the market to read in that critical range. Alkalinity may be read from the same sample in 0.5 meq/L increments. MultiTestâ„¢ Marine pH & Alkalinity performs over 75 tests and contains a reference sample for validation.
The Nutrafin pH Wide Range Test Kit (4.5 - 9.0) will determine the general range of pH in your aquarium. Most species of fish require specific levels of pH to survive. By classifying your water as acidic or alkaline, you can create a natural habitat for your fish. Nutrafin Wide Range Test Kit is suitable for fresh and saltwater aquariums, and helps ensure optimal water conditions for your fish.
