API Liquid Ammonia Test Kits

For Freshwater & Saltwater : Ammonia (NH3/NH4) : Reads 0 to 8 ppm : 130 Tests

Ammonia, the number one killer of tropical fish, is constantly being produced in the aquarium from fish waste and urine, decomposing plants, and uneaten fish food. By accurately measuring the ammonia level, this kit gives an indication of the efficiency of the biological filter, which helps eliminate ammonia from the aquarium

API Liquid GH & KH Test Kit

For Freshwater : General (GH) & Carbonate (KH) Hardness

The general hardness (GH) and carbonate hardness (KH) of aquarium water should match that of the natural habitat of the fish. Otherwise, fish will be stressed and prone to disease. Since adding tap water increases the hardness of aquarium water, frequent GH and KH testing is imperative.

This kit measures both general hardness (GH) : the measure of calcium and magnesium in water, and carbonate (KH) hardness : the measure of carbonate and bicarbonate concentrations

Proper GH and KH levels are an important part of water quality and are necessary for the health of fish and the development and growth of aquarium plants

Kit contains:

• : Two Dropper bottles for accurate dispensing of test solutions
• : Easy-to-read instructions and colour chart
• : Non-staining glass test tube with snap-tight cap

Made in the USA 

Price:   £5.29 (Including: VAT at 17.5)

API Liquid KH Test Kit

For Freshwater & Saltwater : Carbonate Hardness

The carbonate hardness (KH) of aquarium water should be tested frequently, since water with a low KH is subject to rapid shifts in pH, greatly stressing fish and making them vunerable to disease.

The kit measures carbonate (KH) hardness, the measure of carbonate and bicarbonate concentrations in the water. The proper KH level is an important part of water quality and is necessary for the health of fish and the development and growth of aquarium plants

Kit contains:

• : Dropper bottle for accurate dispensing of test solutions
• : Easy-to-read instructions and colour chart
• : Non-staining glass test tube with snap-tight cap

API Liquid Calcium Test Kit

Calcium is one of the most important elements in a reef aquarium.

Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy.

Over time, calcium levels drop as invertebrates use calcium in aquarium water.

This kit allows you to easily and accurately measure calcium levels and maintain a healthy reef aquarium.

* Measures calcium levels as low as 20mg/L
* Uses titration method, with easy to see color change for precise measurement.
* For use in Saltwater Aquariums

Testing Tips

The Calcium Test Kit reads the calcium concentration in milligrams per liter (mg/L) which is equivalent to parts per million (ppm).


Kit Contains :

* Child resistant safety caps
* Two dropper bottles for accurate dispensing of test solutions each containing 37mls
* Easy to read instructions and colour chart
* Non-staining glass test tube with snap-tight cap 

Price:   £7.95 (Including: VAT at 17.5)

API Liquid Phosphate Test Kit

Phosphate can enter your aquarium or pond through tap water, fish waste, and decaying organics such as uneaten food and dead algae.

Excess Phosphate contributes to unsightly algae blooms in aquariums and ponds. In salt water, phosphate can also inhibit the growth of corals and other reef building organisms.

This kit allows you to easily and accurately measure the phosphate level and maintain a healthy aquarium or pond.

* Tests phosphate levels from 0 to 10 ppm
* Performs 150 tests
* For use in Freshwater or Saltwater Aquariums or Ponds
