Reborn calcium reactor media is harvested from a sustainable source in the Western Pacific Ocean. Two Little Fishies pre-rinses their media in RODI water, as well as manually removing any snail or clam shells before packaging. Reborn is one of the only calcium reactor medias that still uses legally sourced coral bones and our preferred choice for a low cost calcium reactor media that will not clog like many others in a calcium reactor.
Replenish calcium and carbonate alkalinity for the proper skeletal growth of your corals.
It was a good experience but i was told that it was the large grain not the small as I ordered the large shown in the picture. I received the small and decided to use it anyway. But overall the experience was good.
