Tetra Test 7-in-1 Water Test Strips – 50 Pack
Test your aquarium water in under 60 seconds — no droppers, no mess, no guesswork. The Tetra Test 7-in-1 Strips give you a complete snapshot of your freshwater aquarium's health with a single dip. Whether you are cycling a new tank, troubleshooting sick fish, or doing routine weekly maintenance, these strips tell you exactly what is happening in your water — fast.
The 50-strip pack is the ideal middle ground — a solid supply for hobbyists testing one or two tanks weekly, giving you approximately 3 months of consistent weekly testing without the commitment of the bulk pack.
