These are accurate and easy to use. A good alternative to the master test kit. The color codes are easy to read and understand, which makes this user friendly for almost everyone. Very much would recommend.

Easy to use/read great price

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

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

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!!

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.

Easy to use and have been accurate as long as I’ve been using them! Love the amount I received and I feel really good about the results and know that my guy is swimming in safe waters!

I se this every week and chat gpt reads them very nice
