Standard filters remove unwanted materials from the water, but mostly only if they are made of solid particles. It is easy to remove salt, sand, and other solid stuff from the water because most filters are designed to separate the liquid from the solids. They do an excellent job, of course, but it isn't enough. What if the unwanted materials in the water are tiny particles? What if they are liquids?
You need more than a filter, obviously. What you need is a trusty bottle of Seachem Purigen from Pet Store
. This liquid is an excellent synthetic adsorbent, which is a material that holds molecules of foreign materials on its external surface, forming a thin film. During the adsorption process, the molecules of the unwanted materials stick to the adsorbent, which in turn breaks them down. This may be a simple process, but it sure does work. Seachem Purigen can remove ammonia, nitrates, proteins, nitrates and other organics that may be harmful to aquatic life, but it doesn't harm aquatic life
Seachem Purigen restores the water to its original clarity and goes one step further by polishing it to achieve unprecedented water clarity. This adsorbent is made of synthetic polymers, which remove impurities from the water, both insoluble and soluble ones.
SeaChem Purigen is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others, even HyperSorb, by over 500%. Purigen; removes proteins, nitrites and nitrates, ammonia, and a broad spectrum of organics, yet its impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Like HyperSorb, Purigen darkens progressively as it exhausts, and is easily renewed by treating with household bleach. A 100 mL bag of Purigen purifies and polishes up to 100 gallons of water for up to six months. Purigen is designed for both marine and freshwater use.
