Very easy to read and interpret, great price.
I love that these have the chlorine test strip last, so it's easier to ignore it. Saves a little bit of time- I appreciate that!
Yes 5 stars
First off I love that it comes with such a large quantity because that is way more economical and results in less waste overall. Inside the bottle has laminated card with the color guide that you can pull out, so you're not always having to hold the strip up to the side of the bottle. I also find that these are the most consistently accurate, way better than the API strips. These are so perfect for me since I have multiple tanks that are mostly on autopilot, I can just do a quick test with these to gauge general parameters (and then I can get out the test tube kit if something seems off). Highly recommend!
I was doubtful of the accuracy compared to the api master test kit before buying. After purchasing I did several comparisons with different aquarium waters and was surprised how close they actually were. Having 14 and counting aquarium’s counting drops gets crazy on my eyes, another product well done by aquarium coop!
Does the thing and cost per strip is really good.
These are perfect for quick checks and even testing tap water! Great value, too!
Starting a new tank is overwhelming and I've been really happy to have these. They're easy to use and extremely helpful to gauge how my new tank is doing.
These strips make water testing so easy and convenient. It’s such a significant time reduction from the API master test kit. I’ve compared the master kit and strips and everything has been accurate so far. I highly recommend getting the bigger bottle. It’s such a good deal and is one little thing to make fish keeping easier.
Easy to order, order came very fast and easy to use with clear instructions.
