Elos USA 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.

    REVIEW
    I have used several test kits from API,Salifert to LaMotte and the Elos is IMO on par with the Lamotte. The only issue I have is that the color change from cyan to yellow is too subtle. I would have given it 5 stars if not for this. The test kits are dated which is a good thing. My last kit was ...Read More

    This kit is probably accurate but trying to decipher a color change from cyan to yellow when the colors are so week is a pain. I think I will be sticking with Salifert, just as accurate and no guessing on weak color changes.

    I found the test kit instructions confusing at first but after a few times of testing, it became easier. Over all a very good product, with plenty of testing in each kit.
