Salifert Carbonate Hardness & Alkalinity (Kh/Alk) Test Kit, 100-200 Tests

Great for my testing in koi ponds where greater accuracy is required

Faaaaar more accurate than the strip tests, and easy enough to use. The colour change is easy to see and the instructions are clear. It might initially seem that the strip tests are better value, but you might as well throw £10 in the bin, dip your finger in the water and shout out a random number. These titration tests are absolutely the way to go, and this one in particular gave me exactly what I wanted for a great price.

Love this test kit. Gives me accurate readings. Easy to use with the instructions provided.

Have bought before this has changed to add an additional dropper but again seems accurate and easy to use and replicate

Best you can get

Yea it's a good easy to use test kit. Results are easy to.define too.

I use this om a weekly basis as to use it nice they have the sell by date so you know when to replace great text and salifert is a great test

As usual from Salifert, a great value for money product; It gives instant/accurate results; I have been using this particular test for over a year now and would definitely recommend it; Very easy and simple to use. I used to use it every single day until I managed to level the KH on my nano reef. Now I test it once a week.. This kit deserves a BIG 5 from me.
