If you're treating fish with a copper-based medication, this kit lets you maintain the precise therapeutic dose (too little doesn't work, too much is toxic). And if you keep \u003cstrong\u003einvertebrates\u003c\/strong\u003e, it lets you confirm your water is copper-free, since copper is deadly to shrimp, snails, and other inverts even in tiny amounts.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin:0 0 16px;background-color:#eef2f6;border:1px solid #c7d4dd;padding:14px 18px;color:#1b2731;\"\u003e\u003cstrong\u003eGood to Know:\u003c\/strong\u003e For a shrimp or snail keeper, this kit is genuinely useful peace of mind — copper can leach in from old plumbing, certain medications, or some tap water, and inverts are extremely sensitive to it. It's also essential for anyone running copper treatments in a fish-only\/quarantine tank, where holding the right concentration matters. Good for about 90 tests.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin:0;color:#2c2c2c;\"\u003e\u003cstrong\u003eHow to Use:\u003c\/strong\u003e Add the reagent drops to a tube of tank water per the instructions, wait, and match the color to the chart.
