Seachem pH Alert Reader is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly to alert you shifts to in pH levels between 5.8 and 8.5.

• No strips, no tests, just constant readings
• Detects pH shifts anytime for 3-6 months
• Small and unobtrusive
• For freshwater use only

DIRECTIONS: Simply place Sea Chem pH Alert Reader visibly anywhere in the aquarium or filter. Its that easy. No chemicals or test procedures are required. When first put in service, response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. The life of the pH Alert Reader sensor may vary depending on a variety of tank parameters. A replacement sensor is included to ensure effectiveness for 3 to 6 months. Sensor exhaustion is indicated by a visible fading or washing out of sensor color.

Aquarium Pharmaceuticals Fresh/Salt Water Carbonate Test Kit measures carbonate hardness, the measure of carbonate and bicarbonate concentrations in the water.

• Carbonate hardness test kit
• Monitor KH to prevent pH problems
• For freshwater aquariums

APIs carbonate hardness (KH) of aquarium water should be tested frequently, since water with a low KH is subject to rapid shifts in PH, greatly stressing fish and making them vulnerable to disease.

The proper KH levels is an important part of water quality and is necessary for the health of fish and the development and growth of aquarium plants. Kit contains dropper bottle for accurate dispensing of test solution, easy to read instructions and color chart, non-staining glass test tube with snap-tight cap.

Aquarium Pharmaceuticals Phosphate Test Kit allows you to easily and accurately measure the phosphate level and maintain a healthy aquarium or pond. It does 150 tests.

• High phosphate leads to algae growth
• Helps maintain clear and healthy water
• For fresh and saltwater

Why test your phosphate levels Well, phosphate can enter your aquarium through tap water, fish waste and decaying organics such as uneaten food or dead algae. As phosphate increases so does your chance of having unsightly algae and green water blooms. In salt water, phosphate can also inhabit the growth of corals and other reef building organisms.

Kit contains: two dropper bottles for accurate dispensing of test solutions, easy to read instructions and color charts, one non-staining glass test tube with snap-tight cap.

Range is as follows for freshwater and saltwater: 0.0 PPM, 0.5 PPM, 1.0 PPM, 2.0 PPM, 5.0 PPM, 10.0 PPM.

Nitrate buildup in aquariums is often an indicator of declining water quality. High levels of nitrate are frequently associated with poor fish health, algae growth, and a build-up or organic pollutants. Up to 90 tests with this API Kit.

Aquarium Pharmaceuticals Fresh And Salt Water Nitrate Test Kit measures nitrate (NO3) in freshwater and saltwater aquariums. The enclosed instruction booklet will tell how to test for nitrate, what the results mean and how to improve water quality and fish health.

Fast, easy and accurate. Reads 0 to 160 mg/L or parts per million (ppm) of nitrate. Child resistant safety caps. The Fresh And Salt Water Nitrate Test snap-tight cap.

The API Ammonia Test Kit measures ammonia levels in both fresh and saltwater aquariums. Ammonia, the number one killer of tropical fish, is continually produced in the aquarium from fish waste, decomposing plants and uneaten fish food.

• Ammonia NH3/NH4+ test kit
• Monitors toxic ammonia to help prevent fish loss
• For fresh and saltwater aquariums

Ammonia in the aquarium will damage delicate gill membranes and prevent fish from carrying on normal respiration. High levels of ammonia quickly lead to fish death. Even trace amounts can stress fish, suppressing their immune systems and thereby increasing the likelihood of disease and subsequent fish loss.

This fast, accurate and easy-to-use kit contains: 2 dropper bottles, test solutions, easy-to-read instructions, color chart and glass tube with lid. Provides 130 tests for ammonia levels from 0 to 8 ppm.

Seachem Ammonia Alert is an innovative color device for continuously detecting and monitoring free ammonia in aquariums. A sensor changes from yellow to green to blue, relative to the ammonia concentration in the water. Seachem Ammonia Alert detects less than 0.05 mg/L (ppm) free ammonia and alerts you before fish show any signs of stress. It lasts over a year and replacement sensors are available.

• Easy visual gauge to monitor ammonia in your reef or fish tank
• Use in saltwater or freshwater aquariums
• Provides 1 year of ammonia detection

In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. 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 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 register a SAFE reading.

The Seachem Alert Combo pack is a revolutionary way to keep tabs on your aquariums essential levels. This unique tester provides continuous pH and ammonia readings for up to 6 months, eliminating the need for strips and complicated tests.

• Continuous freshwater pH and ammonia readings
• No strips, no tests, just constant readings
• Up to 6 months of constant monitoring

Alert Combo is easy to use: just place each reader somewhere visible in your aquarium, and you're done! After only a few minutes the readers will automatically detect and display your waters pH and ammonia levels using a simple color-coded system, and will continuously update every 10 minutes after that. No care is required beyond removing any algae accumulation with a clean, soft material.

Ammonia Alert works in freshwater and marine aquariums, and provides continuous readings for up to 1 year. pH Alert works only in freshwater aquariums, and provides continuous readings of pH levels between 5.4 and 8.0 for 3-6 months.

Seachem One Year Combo Alert uses Seachem water sensor technology to continuously monitor ammonia and freshwater pH in your aquarium for an entire year, no tests or strips required. All you have to do is hang it in your tank!

• Continuous freshwater pH and ammonia readings
• No strips, no tests, just constant readings
• Easy monitoring - just hang in your tank

Ammonia Alert: The sensor automatically detects free ammonia at levels less than 0.05 mg/L (ppm) and alerts you to the presence of the primary killer of fish before it reaches hazardous levels and causes signs of stress. In the absence of free ammonia the sensor will assume a yellow color, and will move to green and blue as more ammonia is detected. Ammonia is detected continuously with a response time of just 15 minutes, allowing you to respond immediately and avoid further increases. Ammonia Alert lasts over 9 times as long as competing products, and is only about half the size.

pH Alert: pH is constantly monitored, with a sensor that alerts you to shifts in pH levels between 5.4 and 8.0 (freshwater only). It lasts up to 4 times as long as competing products and is small, clear, and unobtrusive when in the tank.
