Abstract
    The author considers the following problems that are inherent to closed marine system: (1) appearance and accumulation of excretory products; (2) depletion of the alkaline reserve and a drop in pH; and (3) accumulation of nitrate, phosphate, sulphate and organics.Data suggests that an acid insoluble, non-organic coating on culture system filters may act to reduce the buffening activity of the gravel filter and that dry tumbling may be necessary to restore this activity. Mass algal cultivation within closed marine culture system may be used to curtail nitrate and organic accumulations.
