CaribSea Seaflor Special Aragonite Sand for Marine Aquariums – 15lb

CaribSea Seaflor Special Sand is a premium aragonite substrate designed to enhance aquarium appearance while supporting biological filtration and stable water chemistry. Part of the trusted CaribSea substrate range, Seaflor is ideal for marine and reef aquariums, providing a clean, bright white sand bed that complements coral and fish displays.

This natural aragonite sand helps buffer aquarium water to a stable pH of around 8.2, making it especially suitable for reef tanks and systems that require higher pH levels. It can also be used successfully in aquariums housing African Rift Lake cichlids, where stable, alkaline conditions are essential for fish health and reduced stress.

Seaflor Special Sand contains naturally occurring calcium, carbonate, and trace elements that are gradually released into the water column. These elements help replenish nutrients that become depleted in busy aquariums, supporting healthier livestock and long-term tank stability.
