Imagine 100x turnover for a 300 gallon tank. At 30000 gph, forget the current. How on earth do you pay the electricity bill...
I think you would need maybe 4 or more swimming pool pumps at about 1.5 horsepower each and a 3 phase electric hook up and a large dedicated supply, each pump would need 1.5 to 2" tubing and the filter would normally be sealed and running around 15-20 psi...my pool runs one of these pumps and it bruises my hand if I put it in the way of the suction and saftety guards need to be put in place....just one pump would pull the fish and the sand clean out of the tank I think, if not blow it all to one end. I cannot cover the venturi return back to the pool with my hand as the pressure is way too much.
I do not think this would be practical for me.
