After a harsh winter here in Connecticut, I found out a few of my koi fish had died. Afraid that it might be more than the cold that did them in, I did some research on water test kits and ended up going with this one after reading the reviews on Amazon. Once I received them I followed the simple instructions. Basically you fill the little glass vials with pond water up to a certain marked level, and then you drop a certain number of the included chemical drops in the vials. After a very short time the water turns a certain color, and you compare it to a supplied water chart. This is how you know if you have too much or too little of a certain chemical or issue in your pond. It's very easy to do. I learned that I had too much of certain water pollutants in my pond, and after doing a quick online search I learned what I had to do to get the readings to be normal again. A week or two later I rechecked the levels and everything was perfect. Since then I've had no more fish deaths and I thank this test kit for that! I've learned things as simple as a rain storm can affect your pond water quality, so this kit is great to do occasional tests to make sure that the water is normal so the fish can thrive. It's very simple to use and there's enough chemical drops to do many, many tests in the future. This kit will last a very long time. I'd highly recommend this to anyone with a pond at their home.

Práctico y exacto. No sé si se puedan comprar por separado los reactivos, cuando éstos se acaban
