Review on 🐠 Enhance your Aquarium's Quality with SJ WAVE 6-in-1 Test Strip - Accurate Water Testing for Freshwater Aquariums & Ponds (100 Tests) by Nick Owens

These strips are very easy to use once you learn to read them. Instead of matching the stripe to a color block (like I did), hold it between two colors to see if it matches. I love that they test all the important water quality factors in one test. No test tubes or hazardous test chemicals. The only complaint is that some of the test pads fall off the strip.
