Review: Worth the price - Worked as described and is accurate.
Review: Great deal; great product - The ammonia alert is super helpful in teaching my daughter the need to change the water in her betta nursery weekly for her fry and reenforcing avoiding overfeeding. She just needs to watch the color daily. And she gets to see it become yellow again after a 50% water change. Great monitoring and teaching tool. Warning, if you are using leaves, cones, or wood for tannins in your tank for shrimp, it discolors the pH disc and makes it harder to be sure of the colors. In tanks without tannins added it is very easy to read and quite accurate. I highly recommend for beginning hobbiest or those who want an easy way for a daily check. Especially for nano tanks where balance can change quickly overnight or small betta environments. But great for all freshwater set ups. 1st two stained by tannins and need replacing. They do not match water tests. Package does come with 1 replacement for pH at 6 months time frame. Be sure not to throw away! Photos from 3 different set ups. 1st two are tannins stained and need replacing. Environments water test at a 7.0 to 6.8 range. Do not use pH cards in an environment with tannins.

### ⭐⭐⭐⭐ Works as it is intended; easy to misunderstand
*by M***S on July 26, 2020*

Before claiming these are inaccurate, research total ammonia vs free ammonia. These will provide a different ammonia reading than strips or droplet tests because those are total ammonia. If anything, these are more accurate because they show only free ammonia (the ammonia that can hurt fish). Just be aware of you use an ammonia “reducer” this will show the ammonia is gone, which may lead you to think the problem is solved. Then the ammonia will be “back” right after the Prime or whatever wears off in a few days. I like using this during cycling, because that’s when you especially need a little ammonia present to start the cycle but not enough to harm fish. It’s also a good day to day visual reminder. I do still test total ammonia weekly. The pH is hard to read, it confoundingly goes darker and lighter and darker again around the circle and doesn’t match the dot well. But the point of pH is to be stable, not hit a specific number. This “1 year” pack includes 1 each and an extra stick on dot for pH because that one lasts 6 months. Good luck keeping track of that tiny dot. I wish it just had 2 pH wheels or was clear that it’s a starter kit and you replace the pH earlier. At any rate it’s a great value and very helpful *along with* more thorough testing, good knowledge of the nitrogen cycle, and frequent water changes.
