API Replacement Test Tubes For Aquarium Liquid Test Kits, 24 count

Streamline Your Testing Routine

If you own multiple aquariums or use the API Master Test Kit, you know that four tubes are rarely enough. Whether you’ve dealt with a "clumsy drop" on a tile floor or you're tired of washing and drying tubes between every test, this 24-count bulk pack is the ultimate upgrade for your aquarium lab.

Professional Quality for Accurate Results:

• Crystal Clear Glass: Made from high-quality, laboratory-grade glass that won't cloud or stain over time, ensuring you get an unobstructed view of your color results.

• Snap-Tight Safety Caps: Each tube comes with a secure, leak-proof cap to prevent chemical spills and skin contact during the "shaking" phase of your nitrate or ammonia tests.

• Universal Compatibility: These are the exact OEM tubes used in all API liquid test kits, including the Freshwater Master, Saltwater Master, and Reef Master kits.

• The "Multi-Tank" Solution: With 24 tubes, you can draw samples from all your tanks at once and run your tests in a single "batch," saving you significant time during weekly maintenance.

Why Buy the 24-Count Pack?

• Eliminate Cross-Contamination: Dedicated tubes for different tests (e.g., one for $pH$, one for $NH_3$) ensure that residue from one reagent doesn't interfere with the accuracy of another.

• Stop the "Wash & Wait" Cycle: No more waiting for a single tube to dry. Line them up, dose them all, and get back to enjoying your fish.

• The Ultimate Backup: Glass breaks—it’s a fact of the hobby. Having a bulk supply on hand means a broken tube never stands in the way of a critical water parameter check.

Care Instructions:

• Rinse thoroughly with warm tap water after every use.

• For stubborn reagent stains, use a dedicated tube brush and white vinegar.

• Air dry upside down to prevent water spots.
