API pH TEST & ADJUSTER KIT 250-Test Freshwater Aquarium Water pH Test and Adjuster Kit

Easy & works great

Easy to use and Precise, this kit allows you to choose your desired Ph after you get your first reading, just follow the Directions

I have mystery snails and it’s important to keep the pH of the water at a certain level. This kit is a fast, easy way to make sure it stays where it should, and comes with pH up and down so you can correct it immediately.

I've tested multiple tanks and tap water with this test kit. ALL READ THE SAME PH. (I have used other tests to verify the accuracy of this test....All my waters that I mentioned are different PH). the only reason I rate this 5 stars is so that hopefully it can be seen by others. If there was an option for 0 stars I would rate it as so. False testing. I have tried this brand before and never failed me. Funny when I order the product off amazon its either boof or broken somewhere. When I tried to get a refund or even replace it, its under a category that "isn't eligible for refund" What a great way to waste money. I will never be ordering any API liquid testing kits off of amazon ever again!!!

I actually don’t have fish but I have a snail and I test the water once a week and this is so helpful in finding out if I need to add anything to the water to maintain it for his health.

Good price and quick shipping

If ph is what you're concerned about this is a good little kit. Does the job and is simple to use.

I have had an established fresh water tank for years. Had an amazing PH test and repair kit that I'd purchased at a store many years ago that had powered repair chemicals instead of liquid - it came with the tube, very detailed instructions and only cost about $20. When I relocated to CO from FL I didn't bring my 55 gal tank because I knew the transition would likely kill the fish so I sold the entire set up. I missed having fish so much I decided to start with a small 20 gal. Since I had no idea the PH of my well water I purchased this kit - unable to find the type of kit I had originally. I do not care for the liquid additive but the biggest issue is that the instructions tell you how to test the water but not how much PH up or down to add to balance the water. I had to look the information up on line. Since my water was very alkaline I found it difficult no matter how much PH lowering liquid I added to get anywhere near a more neutral PH level - after some serious research I found that most fresh water fish are find in a more alkaline environment so I've given up trying to balance the water and the fancy gold fish and African pygmy frogs I have in the tank are doing just fine.

The scale only goes up to 7.6, so useless for a cichlid tank. The pH up/down instructions tell you how much to add, but not what the expected change is. My pH was high off the scale (blue), but there i no way to know how high or how much acid to add.

Conforme à mes attentes. Fonctionne très bien.

Works very well tests last for ages and keeps a good check on your ph levels. would recommend to all.

3 Bottles in one pack but different expiry dates. From Dec 2025 to Jan 2026 Looks like old stock as its Mar 2024 now. My old PH Test Solution bought in Singapore had expiry date 3+ years from when bought
