Seachem Renew 100ml Phosphate-Free Carbon Alternative Filter Media

Seachem Renew 100ml is a high-quality chemical filtration media designed as a safe alternative to activated carbon that may release phosphate into aquarium systems. It effectively removes organic waste and particulates while remaining completely phosphate-free, making it ideal for reef and planted aquariums.

Unlike some activated carbons that can raise pH levels, Renew does not affect pH, making it especially suitable for softer water conditions. It is used in the same manner as traditional activated carbon and delivers excellent water clarity without compromising water chemistry.

Seachem Renew is best placed in a high-flow area of the filter using a media bag and should be replaced every 4–6 weeks for optimal performance.
