ELOS AQUA TEST KIT- CARBONATE HARNDESS The alkalinity of a solution refers to its capacity to buffer against drops in pH. It is a measure of the concentration of various negatively charged ionic compounds (anions) such as carbonates, bicarbonates, borates and hydroxides in the aquarium water. The concentration of these ions determines the buffering capacity of the water to maintain proper pH. If the percentage of the hydrogen carbonate and carbonate ions is too low, the pH value of the water may drop severely (acidity drop) causing a life threatening condition for many plants, invertebrates and fish. The ideal value of KH in a saltwater aquarium is 7-10 dKH° and for a planted freshwater aquarium is 3-7 dKH°. Because of the importance of KH, it is necessary to keep the proper KH level by testing it with an accurate test kit. ELOS AquaTest KH, as well as all the other titrimetric test kits of this line will grant very high precision thanks to several procedures like the use of calibrated droppers with constant and predefined drops of 0.05 ml each, the validation of our reagents through NIST (National Institure of Standard and Technology) validation and the careful stock management to supply to our customers ONLY the freshest production batch. HIGHLIGHTS: High precision: thanks to the use of calibrated droppers NIST validation: each batch is validated using NIST (National Institute of Standard and Technology) samples. High number of test per kit: up to 60 test (with a standard level of 10 dKH) "Safe reagents": reagents and testing procedures are based on Low Risk Reagents. None of our test kits are based on Toxic Reagents. Customer Reviews Write a review 3 of 4 people found the following review helpful: Average Not what I thought. by CHAD PETERS Experience Level: Expert Posted on 2/12/2008 from FL UNITED STATES Comments: This is a O.K. kit been using sailifert kits for years figured I'd give it a shot. Not what I was expecting. I thought it would be more accurate and read in smaller scales. It in my opinion just gives whole numbers 9-10-11 not very specific don't know if I'm boarder line 9 when it says nine or closre to 10 would like more specific accuracy. Test vile dosn't match up with the glass vial you draw water with. 5ml on the glass vial is under the mark of the water line you draw with the measuring device. Very confusing for a kit that is suposed to be high end. Moer like the Hagen kits and the API kits. I'll just use this kit as a reference along with my others good back up kit not the only kit you'll ever need.Just O.K. I would not recommend this product to my friends.

Excellent KH test kit by BRUCE Experience Level: Intermediate Posted on 2/21/2008 from LITTLETON, CO UNITED STATES Comments: This is the best KH test kit I've used. It's inexpensive, easy to use, easy to read and accurate. For most tests, the full 1 degree result is OK and can easily be converted to 1/2 degree. I now use one test for both my tank and my calcium reactor. Yes, I would recommend this product to my friends.
