EASYTEST [150 Strip] [6 in 1] Aquarium Test Strips, [Freshwater and Saltwater 2 in 1] Test kit Monitoring, Nitrate, Nitrite, Chlorine, Carbonate, Hardness, pH

The strips are accurate from what I've used. I did tests on filtered water vs hose water and seems to have shown the same different results. I would use multiple strips for these and it shows the same results, none of them seem faulty. I've used around 20 for these. Will update if anything seems faulty!

Attached is a photo of it's result comparing to API test kit that I usually relies on. The PH of this strip only goes to 6.4, since the color is more yellow then the 6.4 color, would have to base on this to consider the PH is higher than 6.4. Nitrate is a bit off, but not bad at all. It's comfortable enough to use for casual water check.

This is easy to use but not extremely accurate. If you need accuracy you need to get the API kit.

We have a small tank, just a handful of fish. These strips get the job done. As far as I know they are accurate, I've seen some fluctuating in the balance of the water. They are easy to read and easy to use. They give me some piece of mind that the aquarium is in the correct range.

Works well for my aquarium and readings are fine.

I’ve ordered these many times over the last year and a half and the quality has gone to a half a star but it’s not available. I have 7 fish tanks and the previous batch kept my tanks in order just fine I worry about the ones I just got

Easy to use test strips. They make testing my 15 tanks fast and accurate. You can see they work great in freshwater or saltwater!

The strips are easy to read and very easy to use. Saved one of my fish tanks alerting me to low PH!
