- Measures pH, Nitrite, Nitrate, GH, KH, and Chlorine
- Results in 60 Seconds
- Available in Two Sizes: 25 and 200 Tests
- Laminated Comparison Card
Frequently testing your water quality is one of the keys to successful fishkeeping. We developed 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.
This test helps you understand your readings with helpful information and suggestions on the laminated color chart we've included. We created these to make your life easier and save you money when it comes to testing your water.
This is the first test kit I turn to for quick and easy testing. If numbers are off I then turn to a more specific test.
There’s absolutely no reason to by test strips from anywhere else.
A few observations that are repeatable with strips from 2 different bottles (200pk)
- Nitrates register very low for me. Maybe it's the coloration, but I'm always getting 10ppm vs test kit somewhere near 30ppm
- Nitrites. Some pads turn pink even when we're at 0ppm. Of course, I didn't get that in the image below. It's definitely not bleed from the nitrate pad.
- GH is always OH MY GOD (>300ppm) high with this, whereas my kit puts it at 11° (~180ppm)
- KH is low as well. Testing around 7° on average (125ppm) and the strip is low at about 60ppm.
- PH with the master kit is about 6.8 with CO2 saturated and 7.0 first thing in the morning (aeration cycle overnight to release CO2). Strips are low, once again, at 6.6 at best.
- Chlorine seems accurate.
With that said, I cannot recommend these strips, especially for a newly established tank.
My new favorite test strip for quick checks on tank parameters. Accurate results.
These test strips from aquarium Coop are great. I checked them with the results from my API master test kit and the results are the same.
These test strips are fast and easy to read. I love all of aquarium Coops items on their website and will continue to buy their products. Shipping was also very fast.
