API 5-IN-1 TEST STRIPS Freshwater and Saltwater Aquarium Test Strips 4-Count Box

If you are using these for saltwater DON'T!!!!Save your money and get a hanna checker.These strips had me thinking i was doing good until I bought a hanna and realized the strips was way off on readings. You'll kill your tank depending on these strips.

This is definitely a must have. My fish was acting strange and looked like he was dying last night so I gave him an epsom soak while I did a water change, because I figured it was the water. He perked right up. It was the strangest thing. I unfortunately didn’t have any testing strips so I ordered these and they got here the very next day. I tested the water and the nitrates and the ph were pretty high still. So did another water change today and now I have happy fish. The tests are reading normal. I’m not an experienced fish keeper and never thought of checking the water conditions I just put water conditioner in and called it good.. I know, I’m terrible.. but after last night these are a must have for me. They're super easy to read and seem to be pretty accurate.A little tip. I cut each strip down the middle so that I have even more tests. They’re still really easy to read. Just be careful

Package came completely soaked in a brown paper amazon softpack. Packaging should be waterproof for paper products

Did not know how much God I'd play to my fish environment and these test strips played the major part in maintaining my roll lol. Seriously perfect especially for beginners like myself!.

These work absolutely amazing i tests my water before and after a change before it said the ph was really high after it said it was lower what is exactly what I was hoping for

This test trip is confusing for me because it don’t tell if the range is safe, harmful and it don’t includeAmmonia. But it does give you the rest of the results and I use it for that.

Con estos strips puedo tener el control de lo qué pasa en el agua de mi pez! Súper recomendable el

Worked great.
