In 1995, David Fregger invented the world's first computer operated aquarium surge tank (COAST ™) system.

In addition to the COAST ™ systems, Fregger designs and builds a variety of living reef aquariums that showcase his signature craftsmanship and artistry. From 4.5-gallon Mini Reef ™ aquariums to systems exceeding thousands of liters, Fregger continues to stand out as one of the industry’s most creative and visionary minds.

ATS's proprietary software allows aquarists to monitor and control water levels (tides), waterfalls, surge activity, and lighting on site and via the internet. More than simply simulating the natural rhythms of a reef, the COAST™ system replicates the vital plant-and-animal exchanges that sustain global ecosystems.
