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)

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

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!
