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

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.

Easy to use. Helping me keep my pond fish stable

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

I have struggled finding a convenient and reliable pH testing method. The API Low Range and High Range for freshwater aquarium are too inconclusive between 7 and 8 which drives me crazy (plus you have to make 2 tests) and pH pens are unreliable in my experience and you have to recalibrate them all the time. Test strips are useless (I tried several of the best rated brands on Amazon). I felt upon this test and decided to give a try. It is marketed as pond product but works very well for freshwater fish tanks too in my opinion. The color reading is scaled at a 0.5 point increments which is higher than for the low range and high range API kits, but I don't need 0.2 point precision on pH. I do need though to know for exemple if the pH of my tanks is under or over 7.5 has this is the upper comfort zone limit of some of the fish and shrimps I keep, which was impossible to do with the other kits, plus you only need one test. Simplified my fish keeping hobby and gives me peace of mind.

That's one chemistry that makes you a better living. Liquid tests are always more precise than strips and, when it comes to pH, probes. However, I always found it a hassle to have to run two pH tests with standard API master kit, as they have separate reagents for low and high pH. This one gives great color scale from 5.0 to 9.0, only 5 drops, and has a very reasonable price. I haven't used my pH probe in months now.

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.

Great product - includes test vial

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..
