Nothing special, they work. Be careful on how much you use because you only have 25 of them which can go by FAST.

These are a must have. My water parameters have been on point since I purchased. Very happy customer.

Great way to quickly check if you don't have very much time

I use this for my Axolotl and my Community tank. I avoided getting these because I was being cheap in the start of my hobbying with aquariums. This is probably one of the first things you should get! The value the information provides by far outweighs any price tag for the health of your loved pets. My Axolotl is still growing up, so I am able to track how fast his waste accumulates and how often I need to adjust cleaning his tanks

Good KIT but Nitrites too slow to show as compared to the API Master Kit.

Is not accurate enough to depend on.

When I purchased these I was hoping my life as a fish mom would be made a bit easier, but it wasn't. I was confused by the plastic covering the test part of the strip, and so I called the company that makes this product to ask about it. From the mouth of the representative I spoke with, the plastic on the top of the test square is intentionally placed. It is done this way so that the reactive chemical on the strip to test for ammonia, is not over exposed. This is not done to protect the pad before use, so peeling it apart/open is not intended/recommended. Apparently the water you're testing is meant to seep through the open sides of the strip when you expose it, and then give you a reading after the mentioned wait time. However I tried this multiple times, and saw no changes to the strips when compared to unexposed tests or after ripping off the plastic covering and retesting. I have since decided to return these for a refund and chose to buy from aquarium co-op instead, as they sell a version that not only works accurately but comes in a 100 count for less money. Lastly for those also curious like I was, the ammonia test strips are made separately from the 5 in 1 test strips as the chemical to test for ammonia would produce incorrect results for the rest of the things you're testing for with the 5 in 1 one strips. It's not just for marketing purposesyou're welcome.

Love this, easy to read and good price

When you can't do the master kit, these are just as good.

These are easy to use! I wanted something that tested for multiple things. I didn't want to have to do something complicated and mess with tubes of water. These are great! Keep my fish healthy by monitoring my water weekly.

I have used about 30 of these testing strips over the past month. They always tend to show the same exact results and no indication of nitrite or nitrate ever. Finally I took my water to get tested at the aquarium shop and they told me I had absurd levels of nitrite! I changed my aquarium water immediately but was astonished that not even a single testing strip worked properly.

No directions; no chart for measurements. Blank bottle without branding as API.

Ammonia test kits can be a pain with the process to get a specimen to read and matching it to the color tints. This kit I'm sure is off by 5 but to get a rough ball park of where your ammonia is at then I would suggest them. Dip them in for 2 seconds then match the color to the color pallet on the label. Simple and quick. If your looking for an exact measurement then I would suggest some of the higher end brands that of course are twice the cost.

These are so much easier to use than the liquid bottles. I will still use the test tube liquids every 2 or 3 weeks but these are a quick and easy fast check. The price is also good, although I have found twice as many for about $4.00 more at another store.

Test strips give the same reading as the more complicated and time consuming liquid testers. Yes we're talking only 5 minutes, but why wait with the availability of a quick and easy test.

ive tried these and prefer to the kit w/ vials

All the measurements I need to know in at my finger tips. As a new tank owner you always want to make sure that your tank is in “perfect” condition. Since the bottle has specific levels that range from low toHigh, It won't tell you what actually “good” and what's “not good”. Doing more research is what helped me understand how to read the levels

But these, end of story

They were inaccurateCustomer service none too helpful.
