Two Little Fishies NPX Bioplastics Nitrate & Phosphate Reducing Polymer Media
NPX BioPlastics are pelletized biodegradable polymers that prov
ide a time-released source of food for bacteria that assimilate nitrate and phosphate. As bacteria develop on the pellet surfaces, excess growth sloughs off due to the tumbling in a fluidized filter, and these bacteria can be removed with a protein skimmer or serve as planktonic food for filter-feeding invertebrates such as corals, clams, and sponges. Anaerobic zones also develop within the pellets, thus promoting denitrification there. Why bother with dosing Vodka daily when you can just use NPX BioPlastics and let the bacteria work for you?

Hagen Marina Air Pump
The Marina 50 air pump combines high performance output with quiet operation. A reliable source of air for increasing water
movement and turbulence for proper oxygenation, and can also be used to operate items such as air stones, air curtains and air-actuated ornaments.

Sound dampening pump cover, soft rubber feet suppress vibration and durable, long lasting diaphragm.

Hanna Instruments Low Range Phosphate Meter
Phosphates are particularly important for the growth and development of plant roots, and hence are one of the most common fertilizers used in agriculture. In addition, phosphates are us
ually utilized in detergents and are needed, in small quantities, for heating systems. However, high concentrations of phosphates can cause environmental pollution: they are for example a primary cause of eutrophication. For these reasons, it is necessary to closely monitor the phosphate levels present in both civil and industrial waste water. Range 0.00 to 2.50 mg/L (ppm). Resolution 0.01 mg/L (ppm). Precision ±0.04 mg/L ±4% of reading. Light Source Tungsten lamp. Light Detector Silicon photocell with narrow band interference filter @ 610 nm. Method Adaptation of the ascorbic acid method.

CoralVue 250 Watt Electronic Metal Halide Ballast
Coralvue® electronic ballasts are an important energy-saving unit used for metal halide lamps. Its job is to fire the lamps and
stabilize the operating current. This ballast can save energy by more than 30%. The ballast has a self-protected circuit, which is controlled automatically. If power is removed or lost from the ballast it will take approximately 7 minutes for the ballast to fire the lamp again. The ballasts are available in normal or dimmable. These ballasts will drive any 250w SE metal halide bulb or 250w DE (HQI) metal halide bulb.

ATI T5HO Aquarium Bulbs
Manufactured with high-quality phosphors and advanced manufacturing techniques to produce bulbs with higher output, better coloration and more stability than other brands, including
other German-made T5 bulbs.
