API POND WIDE RANGE pH TEST KIT 160-Test Pond Water Test Kit

Excellent

Easy to use. Helping me keep my pond fish stable

I use this tester for my aquariums and outdoor pond and appreciate it's ability to measure PH all the way from 5 up to 9. Now I don't have to buy two separate test kits to measure low range and high range ph. I find it as easy to read as the narrower range test kits and it's just as accurate for my color vision abilities (which are limited). It may not be the best kit if you are looking for precise readings such as 7.3 vs 7.2 but it gives an accurate enough result for my needs.

Works to back up my digital ph reader, always good to double check koi are expensive

I needed the wide range for daphnia and brine shrimp and this one appears to be good. On an occasion or two I get a very odd reading, but I retest by swirling the water and doing it again. Stagnant water can read differently at the surface than in the middle.

very helpful with testing my pond

Comes with a bottle of chemical,a capped glass test-tube and a wide range pH color card. Pour 5 ml of water sample into the marked test-tube, add five drops of chemical, cap and mix, then compare it to the color chart. The card has scales/colors of 5.0(orange/red), 6.0, 6.5, 7.0, 7.5, 8.0, 9.0(blue) easy to tell the pH difference unless you are colorblind. I have added the acetic acid and sodium bicarbonate to water samples and observed the color changes, so I know this thing work. Also, I have tested it with water samples with known pH, the accuracy is pretty good. The only downside is it doesn't come with an expiration date. For an amateur aquarist like me, this is the startup kit.

Glass tube with cap is not in box and color chart is smudged as if it was used before. Luckily I have 4 glass tubes from an API aquarium test kit. The test solution is accurate so I will keep this kit. I have spent hundreds of dollars on API products over the years and never had any issues. A first-time user of this kit would have had problems from the start.

I've used multiple types of API test kits for my pond and aquariums. Instructions are clear, their kits are easy to use and interpret. The results are accurate when I compare them with other test kits I have. The color chart is reasonably easy to interpret.

It helps to keep your aquarium water clean. Simply dive a stick into the watedr, wait a little bit and check what is your water quality. Very useful kit

Great product

Arrived on time. Works perfect and way more accurate than the Ph strips.

Very easy to use..
