Test Kits

Taking a few minutes each week to maintain and monitor aquarium conditions is the key to a healthy aquarium. The Freshwater Master Test Kit tests the parameters that affect the health of freshwater fish: pH, High Range pH, Ammonia, Nitrite and Nitrate. The The Freshwater Master Test Kit is highly accurate and economical. For ease of use, it comes with 4 glass test tubes with snap-tight caps & a convenient holding tray. The kit also includes a complete, step-by-step instruction booklet with computer calibrated color chart which provides information on how to correct unsafe water conditions.

Benefits:

• Tests pH, High Range pH, Ammonia, Nitrite & Nitrate
• Scientifically accurate for professional results

Ammonia Alert® is an innovative colour device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use.

In the absence of free ammonia the unit will assume a yellow or faint yellow-green colour. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.

Ammonia Alert® lasts over 9 times as long as competing products (over a year compared to 4-6 weeks). Ammonia Alert® is also almost half the size of competing products (1.5" x 2.5"). It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.

Water testing for experienced aquarists

Experienced aquarists check their aquarium water regularly. This allows taking measures, for instance against algae, quickly and easily, without the need to use chemicals. The sera aqua-test box contains the following test kits:

• pH value (pH)
• total hardness (GH)
• carbonate hardness (KH)
• ammonium/ammonia (NH₄/NH_-3)
• nitrite (NO₂)
• nitrate (N₃)
• phosphate (PO₄)
• iron (Fe)
• copper (Cu)
• chlorine (Cl)

Tests tap water & fresh or saltwater aquariums for carbonate hardness (KH). Can be used to determine the proper dose of pH buffers.

Use to measure pH changes in marine aquariums, aquariums with African cichlids, and very alkaline tap water. Reads the pH of water within the high range of 7.4 to 8.8. 160 tests per kit.

pH is the measure of acidity of water. A pH reading of 7.0 is neutral. A pH higher than 7.0 is alkaline, and a pH lower than 7.0 is acidic. Maintaining the aquarium at the proper pH ensures optimal water quality. The pH should be tested weekly, since natural materials in the aquarium (such as fish waste and uneaten food) can cause pH shifts.
