Tests tap water & fresh or saltwater aquariums for carbonate hardness (KH).
Can be used to determine the proper dose of pH buffers.
What is Carbonate Hardness?
Carbonate hardness (also known as alkalinity) is the measure of carbonate and bicarbonate ion concentrations dissolved in water. These minerals are present in municipal, well, and bottled spring water. The level of carbonate hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone. Carbonate hardness helps stabilize pH in the aquarium. An aquarium with a low kH level (50 ppm or less) will tend to be acidic. Aquariums with very low kH are subject to rapid pH shifts.
Directions for Testing Carbonate Hardness (KH):
1.Rinse a clean test tube with water to be tested.
2.Fill the test tube with 5 ml of aquarium water (to the line on the test tube).
3.Add carbonate hardness test solution, one drop at a time, holding dropper bottle upside down in a completely vertical position to ensure uniformity of drops. After first drop is added, solution will turn blue.
4.Cap the test tube and invert several times after each drop. Keep count of the drops being added. Do not hold finger over open end of the tube as this may affect the test result.
5.The test is completed when the water in the test tube, after having been shaken, turns from blue to yellow. If you have difficulty discerning the color after the first drop of test solution is added, remove the cap from the test tube and while holding it over a white background, look down through the tube.
6.The carbonate hardness value is determined by the number of drops of the reagent that must be added to turn the water in the test tube to bright yellow.

AQUAEL UNIFILTER UV is designed for the cleaning and aeration of aquarium water. Apart from efficient water filtration, the device sterilises water using ultraviolet LEDs. This prevents the growth of floating algae, protozoa and bacteria, which results in increased water clarity and a healthier environment for fish. UV LEDs can be switched on and off independently of the filter. UNIFILTER UV is easy to operate. Its performance can be adjusted by means of the dial formed by the rotor dome. The direction of water outflow can be changed by up to 90.
The UNIFILTER UV are equipped with a ceramic rotor axis for even quieter operation and enhanced durability.
The specially designed filter media chamber prevents water from flowing out of the filter and into the fish tank during water changes or when the filter is removed from the aquarium e.g. in order to change the water or wash the sponge. To facilitate the maintenance of UNIFILTER UV, we provide two separate sponge cartridges, which can be removed and cleaned in turns. In this way, colonies of nitrifying bacteria, essential for nitrogen processes, are protected. In order to provide uninterrupted filtration, it is recommended that sponge filter cartridges should be cleaned in turns and independently of each other.
