Results in 60 seconds
Available in two sizes: 25 and 200 tests
Frequently testing your water quality is one of the keys to successful fishkeeping. We developed the Aquarium Co-Op Multi-Test Strips to be fast, comprehensive, and accurate — which makes testing your aquarium water easier than ever. Measure nitrate, nitrite, hardness (GH), buffer (KH), pH, and chlorine levels in just 60 seconds.
When in Doubt, Test the Water
Not sure why your fish are acting weird or if it's time to clean the aquarium? Or maybe you're uncertain about how much fertilizer to add. That's why we made our test strips quick, accurate, and affordable — so you can test the water any time you're in doubt and help troubleshoot potential problems.
Laminated Color Chart
Tired of getting the paper chart on the back of your test strip bottle wet? We feel your pain. That's why we included a second, laminated color chart inside the bottle that you can remove and use for viewing your test strip results. Easy to wipe dry and keep clean.
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.

Accurate and easy
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.

Much faster than liquid tests
I use liquid tests from time to time, but they are very time consuming to do weekly. The Aquarium Co-Op Multi-Test Strips are a very fast alternative that can be done during weekly maintenance. By following the instructions written on the packaging I have not had any issues as described in some of the other reviews. I would 100% recommend these along with most other Aquarium Co-Op products.

Very happy with this product. Love that the nitrates are on top and GH/KH are separated out. I find them very accurate as well! Will continue to buy!
