Complete water quality test kit (215 total tests) – One water testing kit for ponds and water gardens that checks the 4 essentials: pH, ammonia (NH3/NH4+), nitrite (NO2-), and phosphate (PO4³-). Ideal as a routine freshwater test kit for koi and goldfish ponds.
Easy pH test kit + water pH tester results – Fill to the 5 mL line, add drops, cap and shake, then match to the chart. Quick, repeatable pH test results for ongoing pond maintenance (great when you need a dependable pH water tester at home).
Ammonia test kit for fish health (better than guessing) – Catch spikes early after feeding, storms, new fish, or filter cleanouts. A reliable alternative to ammonia test strips for fish tank users who want a clear color-match method for ponds.
Phosphate test kit to help control algae pressure – Phosphate can fuel algae and cloudy/green water. Track trends over time with a true phosphate test kit so you can adjust filtration, feeding, and water changes with confidence.
Freshwater pond test kit + saltwater range chart – Built for pond water testing, with a color chart that also includes saltwater ranges. Includes glass test tubes, caps, transfer pipette, and all required reagents.
