Ammonia Alert™ is an innovative color 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 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, 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.
Why It's Different
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. It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.
As little as 0.02 mg/L of free ammonia will produce a greenish hue on the detector surface. This corresponds to a total ammonia (both ionized and free ammonia) of 0.25 mg/L in marine water at pH 8.3. In freshwater at pH 7.0, this corresponds to 3.6 mg/L total ammonia. Free ammonia is much more toxic than ionized ammonia. As free ammonia, the ALERT color corresponds to about 0.05 mg/L, ALARM to about 0.2 mg/L, and TOXIC to about 0.5 mg/L. The ALERT concentration is tolerated for several days, ALARM for a few days, and TOXIC is rapidly harmful. This product is not recommended for use at acid pH
No care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with fingers, since skin oils can damage it. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor. Sensitivity improves with age, provided the unit is not allowed to dry out, however, drying does not permanently impair the unit. For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Red enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit. The response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle: color should develop rapidly.
Seachem Reef Reactor Lg
Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It has a grain size of approximately 1-3 cm. (Reef Reactor™ Md is 0.5 - 1 cm). It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material. With high levels of both calcium and magnesium, it offers an excellent means of balanced supplementation for rapid growth and propagation of corals and calcareous animals in reef aquaria. It possesses the highest level of soluble potassium of all competing brands while exhibiting the lowest levels of both aluminum and phosphorus.
Rinse Reef Reactor™ prior to initial placement in your calcium reactor. The rate of water flow through the reactor in conjunction with the pH of the water inside the reactor will control the rate of media dissolution. Follow the manufacturer’s instructions furnished with the calcium reactor and adjust the rates of water flow and CO2 injection to attain the desired concentrations of calcium and alkalinity in the effluent.
Use Seachem’s Reef Status™: Magnesium and Reef Status™: Calcium test kits to measure alkalinity, calcium, and magnesium concentrations.
