About This
- FILTRATION: Purigen ranges in color from almost white (cream) to light yellow. Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water.
- SELECTIVITY: Seachem Purigen is an organic filtration resin that works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear.
- CAPACITY: Being both spherical and macroreticular, Seachem Purigen has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.
- REGENERATION: Once Seachem’s Purigen 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.
- SAFETY: 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.

Great Sunscreen
Love this sunscreen. What I like most is that it goes on very dry with zero greasy feeling or shine. The sunscreen is also scent free. I’ve seen several review where purchases stated that they received expired product. Mine arrived in January 2023 and expires February, 2024. I highly recommend this product.

Doesn’t stain clothes and lightweight
Something that always bothers me about sunscreen is how it stains clothing. I did not have that problem with this sunscreen. It was lightweight. It only had a very mild gritty feeling after having it on for over 8 hours and sweating a ton. Best sunscreen out there right now!

The only sunscreen that does not break me out!
I have oily to normal skin with general sensitivity. The breakout-free Neutrogena sunscreens are the only ones that don't break out my face and body, even with reapplication. I have repurchased several times and highly recommend. There is only a slight white cast left over but here's my hack for no whitecast: apply a small amount to fingers and rub to warm, pat to cover face, then rub to blend in, then repeat with another layer. Perfect for underneath makeup, I usually put it on before primer.
