If you're a reefer you've probably heard of World Wide Corals (WWC) before. They are one of the most prolific coral frag shops ever and here we get a little sneak peak of their facility.
Of note:
-It doesn't look like they use sumps on their systems. Each 300gal raceway holds the volume of the entire system, with a skimmer plumbed in externally.
-Each system uses a large Geo's Calcium Reactor with a Carbon Doser.
-A limited amount of live rock, and no sand in the systems.
-Lots of flow from EcoTech Vortech Pumps
-Clove polyps don't tolerate being in small groups very well, always frag at least 3 or more polyps per frag
Enjoy!
