The web designer is still finishing up the site....it should be launched soon.
The closed loop consists of (4) sequence 6000 pumps...two of which are pictured above. These four pumps yield a total flow of 24,000 gph...coupled with the two sump returns brings the total net flow to about 30,000gph.
Feeding is accomplished by using one of my return pumps. There is a feeding baffle around the intake to one of the two return pumps in the sump. So, to feed, all that I have to do is dump the food in this baffle and the pump will take the food up to the tank. This baffle prevents any food from blowing around the sump while it awaits the trip up to the display tank. I feed a variety of frozen foods like mussel, mysis, plankton, etc. Here is a pic of the feeding baffle.
