ABSTRACT:
A marine aquarium or a marine holding system has a tank connected to a closed loop circulation system. The closed loop communicates with an open loop through an osmotic and hydrostatic pressure exchange. A dialysis apparatus for removing undesirable elements is commonly placed into the closed loop and the open loop system. A separate holding tank for a dialysate solution is provided in the open loop system. Canister filters for preparing the dialysate solution by removing unwanted particles and chemicals are tied into the system as well. Peristaltic pumps provide for precise, simultaneous dispensing of a dialysate and a contaminated solution to opposite sides of a semipermeable membrane. The open loop system is connected with a fresh water source, and it includes solenoids, digital times for scheduling events, float switches and time delay relays. The components are connected in such a way as to automatically remove waste products from the closed water loop system. An alternative system also provides for reconstituting the post dialysis water with trace elements that might have been removed by the dialysis process.
