Chemi Pure Elite Vs Purigen: Which One Is Better Pick?

Chemi Pure Elite and Purigen are two products used for filtration purposes in aquariums. Even though they are used in the same manner, they perform differently. But to know which one is for you, Chemi Pure Elite vs Purigen can paint an analytical picture.

Both Chemi Pure Elite and Purigen are great at filtration. Chemi Pure Elite uses an ionization method. These ions attract metals and other byproducts from nitrates, phosphates, and silicates. Whereas Purigen doesn’t work with these ions. It has a polymer with macro-porous. By these synthetic polymers, Purigen can remove any sort of soluble and insoluble products. On the plus side, Purigen can be reused but Chemi Pure Elite can’t. 

Once you know the products and what are your necessities you can choose between Chemi Pure Elite and Purigen. Some users even said that they use them together to get better results. But be sensitive about the lives in the aquarium.

Chemi Pure Elite vs Purigen

If you are confused between Chemi Pure Elite and Purigen then compare these two products side by side. The best way to do this is to know them in different categories. 

Chemical Formation

Chemi Pure Elite

The chemicals present in the Chemi Pure Elite are designed to remove bio-loads and toxic products. The presence of Extruded Pelletized Carbon and Organic Scavenger Resin plays an active role in this filtration. These chemicals of Chemi Pure Elite also work on the removal of algae

Chemi Pure Elite is mostly known for the presence of Granular Ferric Oxide. This is prominently known as GFO. GFO works as iron particles and attracts phosphate and silicates in the water. Then they form a bond and the filter in the aquarium removes the product. 


Unlike Chemi Pure Elite, Purigen doesn’t have active elements. It doesn’t contain any sort of ion mixture. Also, absorbent chemicals are absent in the product. But it has organic filtration resin. 

In Purigen you will find a macro-porous synthetic polymer. The polymer has circular and reticular microscopic pores. With the help of these polymers, Purigen works on both soluble and insoluble impurities. 


Chemi Pure Elite

The specialty of Chemi Pure Elite is that it works best on heavy metals, DOS, Phosphate, Silicates, and nitrogenous compounds. The strength of Chemi Pure Elite is its ionized particles. They attract unwanted and toxic metals and purify the water. 

While working Chemi Pure Elite balances the pH of water by controlling the level of phosphate and nitrate. Also in controlling nuisance algae, Chemi Pure is the best product. Therefore there is no buildup of parasites on the stones or substrate of the aquarium. 

The use of Chemi Pure Elite doesn’t need any iron oxide or phosphate reactor. This saves a lot of money for the user. Also, it can be used without any nylon filter bag. 


In removing the soluble and insoluble impurities that don’t need ionization Purigen is removed by Purigen. The capacity of Purigen to remove insoluble products is over 500% compared to other products.

It also participates in removing nitrogenous organic waste like ammonia, nitrites, and nitrates. The presence of an excess of this nitrogenous organic waste is harmful to the water of the aquarium. 

Also, Purigen is known as the least waste-produced water-purifying product. This means once Purigen is done with refining it leaves almost zero traces. It raises the amount of redox and gives clarity to the water. Purigen has the capability to work efficiently in both fresh and marine water.


Chemi Pure Elite

Chemi Pure is a one-time product. Thus once it does the job of purifying the water, you will need to change it depending on the byproduct produced in your aquarium. 

Generally Chemi Pure Elite needs to be changed after 3-4 months. But in case of heavy loads, it needs to be replaced every 2-3 months. Once the aquarium settles, the amount can be reduced. 


The most beneficial side of Purigen is it is a reusable product. Within a few months of application, the product reaches its full phase. It starts to change color. Then you can use bleach to regenerate it.

The product can be reused up to ten times. In case of heavy biloads the replacement has to be done sooner. If the color changes pretty often, it is the major indication that it is time for a new Purigen.
