8 in 1 Aquarium Test Kit Fish Tank Test Strips Accurate Water Quality Testing Strips for Ammonia PH Total Alkalinity Carbonate Hardness Free Chlorine Nitrate Nitrite Temperature (100 Strips)

Work as expected. Seem to be accurate and work quickly.

Easy to use

Dirt cheap, great results, easy to read. The ammonia part is useless

Easy to use/read great price

Pretty accurate once you figure out what the normal is in a cycled tank

Purchased these to monitor a new tank. I used the strips frequently through the first week, paying particular attention to amonia and nitrate levels. I made adjustments to alkalinity based on these readings as well. All the while, my new fish died one by one. I tested the water using a strip this morning and all looked good. I brought a sample to the fish store, where they used another brand of test strips and also dropper-based tests. Turns out, all the values I had been seeing were way off. The pH was significantly lower, and most importantly, the nitrates were totally problematic (recommending a 75% water change to correct!). The strip had shown 0 nitrates in the same sample!! Although they seemed really convenient, it was too good to be true. These strips are absolutely useless if they're inaccurate. I wish I could return them and am sad that so many fish died in this process. Will be switching to non-strip methods of testing to avoid this in the future.

Best to buy online went to store to purchase and was told cheaper online. They were right , you get more strips for your money. Definitely worth buying!!

Get what you pay for... Not accurate but kinda works on some tests. Chlorine seems to work ok. Ammonia not so much. You really need a liquid test kit. These strips can give you a ballpark. You get a ton of strips for the money. And you get free thermometers to make up for the quality. Okay if you don't need very accurate results.
