We just got our custom sump for our aquaculture coral farm system in from Advanced Acrylics in Anaheim. Sitting in the middle of the sump is our Royal Exclusiv DeLuxe 400 External Skimmer. The return system will be powered by an Abyzz A200 pump. The sump will service six aqua-cultured SPS farm tanks with a total volume of about 1,000 gallons. More pictures to follow shortly.
