Seachem Purigen Review

When I bought my first aquarium, the only thing that seemed to help with keeping it clean was adding a little bit of Seachem Purigen. My tank is always crystal clear and the fish seem healthy ever since I began using this product. The best part about this water treatment is you can find it at almost any pet store or online retailer for less than $20 USD per 1 gallon container.,

Features of Seachem Purigen

1. Unique Synthetic Polymer
2. Regenerable
3. Controls Ammonia, Nitrites, and Nitrates

1. Unique Synthetic Polymer

The Seachem Purigen removes impurities in the aquarium or water to ensure that your fish, plants, and other marine life have a healthy environment. This unique polymer is effective at removing nitrates, phosphate, silicates and more from tap water so you end up with cleaner fish tank environment.

2. Regenerable

Many people are aware that there is a filter in their aquariums, but most don’t know what it does or how to remove the pollutants from water. Among other things, this little gravel-like material helps remove nitrate and phosphate content from your tank’s water – two of the main contributors to algae blooms. In addition, Purigen has a regenerable core which allows for periodic filtering with no carbon media replacement until you decide otherwise.

3. Controls Ammonia, Nitrites, and Nitrates

Seachem Purigen is a small, porous bead that quickly removes the nitrogen from aquarium water. This product can be used in any size tank to remove excess ammonia and nitrites while preventing or reducing the build-up of nitrates. The compact design makes it easy to store at home or take with you when traveling on your next trip.

Reviews & Ratings of Seachem Purigen

Our Rating: 4.7 Out of 5 Stars

Check it out on Amazon-

The Seachem Purigen is a great way to remove the particles that can cause cloudy aquarium water. This product will also help your filter keep up with regular maintenance and reduce waste by using it as part of your main filtration system. One customer said, “I am very pleased with my purchase.” I found 17 reviews at the time of writing and they had awarded this product 4.7 stars out of 5 on average.
The customer reviews are extremely positive overall, but there were a few niggling points raised in some rather minor areas such as “It does not seem to be lasting long” or “A bit difficult for me to use compared to other brands (but) still worth it!”
However, if you’re looking for an effective solution then these are just small hiccups so I’ll recommend this product anyway because otherwise it would have received only 3/5 stars instead which would have been unfair considering how good all the reviews were


Purigen is a product that removes suspended solids from aquarium water. The bacteria take on these particles and bind it with polysaccharides, which is then removed by the activated carbon in the filter media. Purigen can treat up to 50 gallons of tank water per day or 100-200 liters (25-50 gallons) for marine tanks and has been shown to remove nitrate, phosphate, silicate and other common pollutants without side effects. It also requires no chemicals or replacement filters
