This is a fired ceramic disk that does not need to be soaked before using. They are excellent for zoanthid growout and color up nicely in your tank.
Marine Depot was started in 1998 by a self-professed reef geek and premed student Ken Wong. Ken envisioned a one-stop shop where customers could find everything they needed, from technical product specifications, reef aquarium information, expert advice on the hobby and friendly one-on-one customer support. Having grown from a one-man crew to being one of the world’s largest suppliers of reef and marine aquarium products, this very core philosophy still lives strong in the Marine Depot culture 17 years later.
