Seachem Purigen

Seachem Purigen is a premium filter media with the highest organic removal rates. High values of ammonia, nitrite and nitrate can algproblemen care in the aquarium, but remain under control thanks to this unique filter material. Purigen has a huge surface area to impurities from the water filter. Above all, it is the filter material from time to time to regenerate.

Purigen description

Purigen is a premium synthetic absorbent means that is different than other filter materials. It is not a mixture of ion exchangers or absorbeerders, but a unique macro-porous synthetic polymer that is dissolved and non-soluble impurities out of the water remove with a capacity that all other products exceeds by more than 500%. Purigen keeps ammonia, nitrate and nitrite under control by nitrogenous organic waste to remove that otherwise these harmful compounds would be free. The influence of Purigen on trace elements is minimal. It increases significantly the redox. Water is polished to an unmatched brightness. Purigen is gradually thunder as it depletes, and can be easily renewed by treating with turned out to be. Purigen is designed for both freshwater and seawater.

Why does Purigen?

Purigen is a filtration resin with the greatest capacity for removal of organic contamination. No other products come close to the ability to foggy, cloudy water so unprecedented crystal-clear. Yellow discoloration of the water due to driftwood is also counteracted. Different than other products on the market that simple ionenuitwisselingsharsen, Purigen is specifically designed to work on an organic capture resin. When other resins are saturated by the metals and other pollution, is Purigen has barely warmgelopen. Purigen ignores generally the simple elemental compounds, and the extreme preference nitrogenous organic substances. The primary source of nitrogenous compounds is waste. Fish, corals, and even plants produce nitrogenous waste. Purigen removes that waste faster and more carefully than all else on the market.

Capacity of Purigen

Purigen has a higher capacity thanks to its huge surface area. All other resins on the market are only spherical extruded granules. These beads remain even under the microscope, smooth. Purigen is both spherical as macroreticulair. It has microscopic pores that the usable area is many times greater than a just a round sphere. The grains are smaller than 1mm.

Seachem Purigen makes the water crystal clear, removes discoloration, and can many times be regenerated!

Seachem Purigen manual

Rinse before use. Use a very fine filternet (180 microns or less, since the grains are very small). Each 250ml treats such 1000L for up to 6 months. Exhaustion is indicated by discoloration of the beads to dark brown to black. Use 100ml of Purigen per 400 Litres of aquarium water. Overdosing can't. Onderdoseren not, but the material in a shorter period of time need to be regenerated.

Regeneration of Purigen

Purigen can be regenerated. As the waste will absorb, will Purigen change from off-white to dark brown to almost black. Once it is exhausted, can be regenerated with a solution of thin, pale and water. The revealed will is literally the organic material and "burn", from the aquarium water are absorbed. The material is therefore endless. For this make a mixture of one part unscented huishoudbleek to one part water, and leave it 24 hours. Rinse thoroughly afterwards with water, and in water soak. Rinsing and weeks and as long repeat until there is no chlorine smell, to learn more. Or do a druppeltest on the presence of chlorine. TIP: take two servings, so there is always a clean portion can be used during the regeneration of the other and keep this then for the following wisselbeurt.

Available in 100 ml, 250ml, 500ml, 1000ml

Na bijna 40 jaar in de aquaristiek dit topproduct ontdekt bji Azaqua

Ik kende Seachem producten al van in de USA, maar aangezien ze tot voor kort hier in de EU niet of moeilijk verkrijgbaar waren kon ik me er niet over uitspreken. Regelmatig bestellende bij Azaqua merkte ik op dat zij dit nu ook verdelen. Ideale samenstelling om zelfs in combinatie met de Seachem Matrix of zelfs actieve kool te gebruiken. Het geeft een ongelooflijke helderheid aan het water. Regenereren zou ik absoluut afraden aangezien je dit met chloor dient te doen, dus gezien het toch lang meegaat, best nieuw kopen !! Topproduct, wel altijd te gebruiken met "the bag" gezien de fijnheid van de korreltjes !!
