After reading about some of Steve Tyree's SPS tanks and the use of a type of benthic zone or cryptic zones he provides, I decided to make one for myself. The importanace of a benthic zone is to help with water quality and polishing, as well as provide a natural ocean zonation which is presently lacking.
The cryptic area is a dark area in which many sea squirts and sponges and other cryptic organisims live and feed. Tyree has had much success with using this, however I have only heard little mentioned about it.
Has anyone else done benthic zone or cryptic zones?
