The POLY-FILTER is for filtering and purifying both fresh and salt water aquariums. It is a formulation of a special patented material bonded to a synthetic matrix. By means of a unique proprietary process, the POLY-FILTER is made impervious to salt and is also organic loving to certain materials. It can absorb and adsorb contaminants and other toxic materials found in nature or added to fresh and salt water with or without fish and invertebrates. Medication added to fresh and salt water aquariums for treatment of diseased fish will automatically be removed by the POLY-FILTER after serving their intended purpose before the medication can produce a toxic effect on the fish.

PhosGuard is a high capacity and high efficiency filtration product for removing phosphates and silicates from marine or fresh water aquaria. PhosGuard has a working capacity to remove 20 to 60 mg/L phosphate in 100 gallons with a similar impact on silicates. It may be used continuously or intermittently, and will not release removed phosphate. PhosGuard will cause a decline in hair algae and enhance coral growth. Each liter treats up to 300 gallons.

Bio balls are small plastic balls mainly used as the biological media in wet/dry filters. These little plastic bio balls have lots of surface area for the growth of bacteria for filtration.

Contains 3 different carbons in every single pellet, and is used in High Technology Applications. The Tri Base pellets have a stretched absorption scope capable of absorbing an enormous range of pollutants. This breakthrough in carbon technology is used in Medical, Industrial, Environmental, Military, Laboratory and Home applications.
