Seachem Purigen

Seachem Purigen is used to remove soluble and insoluble impurities from water, specifically targeting nitrogenous organic waste to control ammonia, nitrites, and nitrates, while polishing water to exceptional clarity.

  • Highest organic removal capacity
  • Possesses enhanced capacity owing to its vast surface area; both spherical and macroreticular
    Helps control ammonia/nitrite/nitrate
  • Color changes as it exhausts; easily regenerated

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 by over 500%. Purigen® controls ammonia, nitrites, and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen’s™ impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen® darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen® is designed for both marine and freshwater use.

Why It's Different

Selectivity: Purigen® is the highest-capacity organic filtration resin on the market. No other products can compare to its ability to clear haziness and polish water to unparalleled clarity. Unlike other products on the market which are simple ion-exchange resins, Purigen® is specifically designed to be an organic scavenging resin. When ion-exchange resins are filled to capacity by metals and other contaminants, Purigen® has barely begun to reach its potential. Purigen® generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. The primary source of nitrogenous compounds in an aquarium is waste. Fish, corals, even plants produce nitrogenous waste. Purigen® removes that waste faster and more completely than anything else on the market.

Capacity: Purigen’s™ possesses enhanced capacity owing to its vast surface area. All other resins on the market are purely spherical extruded beads. These beads remain smooth even under a microscope. Purigen® is both spherical and macroreticular. It has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.

Regeneration: Purigen® can also be regenerated. As it adsorbs waste products, Purigen® will change color from a pale blonde to a dark brown, almost black. Once it is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally “burn off” the organics that have been removed from the tank. Watch out for products that claim to be regenerable with a brine solution. That is the regeneration procedure for ion-exchange purposes. A brine solution will not remove organics. While such resins have a limited capacity for organic adsorption, a brine regeneration process only replaces removed ionic compounds. It does not destroy large organic molecules that were removed, which is the primary function of organic adsorption resins.

Directions

Rinse before use. Use in a fine mesh filter bag. Each 1 L treats up to 4,000 L (1,000 gallons*) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.

Regeneration: Soak in a 1:1 bleach:water solution for 24 hours in a non-metallic container in a well ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach). Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime®, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 2 tablespoon of buffer per cup of water (Discus Buffer®, Neutral Regulator®). Original color and full activity should now be restored and Purigen® is ready for reuse. Caution: some slime coat products may permanently foul Purigen® and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

Amazing how fast it goes on without the white look!
This stuff is amazing!! I wear baby sunscreen because I rub my eyes a lot, but most of it takes forever to rub in and not look white. This rubs in immediately like any other sunscreen, and it doesn’t burn my eyes at all, not even when I scratch my face and then rub my eyes. So it’s great for small children too, not just 75 yr old ones!

Used for years
I have used this sunscreen since my kids were toddlers. I don’t find it sticky and it turns clear pretty fast. I don’t typically need to reapply on them more than once.

Works great for the whole familiy
Size: 6 Fl Oz (Pack of 2), Style: Lotion Twin Pack
We live in the desert so with the constant sun exposure, our family needs a reliable sunscreen that is affordable, effective and gentle on skin. This product does all that. It has no fragrance and we've had no skin reactions or irritation. It does leave a white cast, which is to be expected given the active ingredients. We are fine with it...it helps show where it's been applied. We use it a lot for pool days so the price point is good to stay stocked up. Don't let the "kids" label fool you...if it works for kiddos, it works for adults too!

Safe, Strong Sun Protection for Little Ones!
Size: 6 Fl Oz (Pack of 2), Style: Lotion Twin Pack
Banana Boat 100% Mineral Kids Sunscreen has become our go-to for sunny days! I love that it’s made with natural, mineral-based ingredients and doesn’t have all the harsh chemicals. It goes on smoothly for a mineral sunscreen—yes, there’s a bit of a white cast at first, but it rubs in nicely and gives me peace of mind knowing my kids are protected with a gentle, effective formula. We’ve used it at the beach, playground, and just running around outside, and it holds up really well. No irritation, no breakouts, and best of all—no sunburns! It’s also water-resistant, which is perfect for active little ones. I’m so glad to have found a sunscreen that checks all the boxes for safety, protection, and reliability.
