ALL OF OUR TROPICAL  & COLDWATER TANKS ARE INDIVIDUALLY FILTERED, AND NOT ON A CENTRAL SYSTEM.

THIS MEANS THAT IN THE UNUSUAL EVENT OF A PROBLEM BREAKING OUT IN ONE TANK, IT IS ISOLATED TO THAT TANK ALONE AND NOT EXPOSING OTHER FISH TO THE PROBLEM.

THE MARINES HOWEVER ARE SPLIT BETWEEN 10 SYSTEMS, 5 OF WHICH ARE SEPARATE SUMPS & THE OTHER 5 ARE INDIVIDUALLY FILTERED, THIS AGAIN GREATLY REDUCES THE RISK OF CROSS CONTAMINATION SHOULD A  PROBLEM OCCUR.
