Decided to buy a pump from from my local hydroponic store instead of Lowes. Fill up the nutrient tank with water. Connected the new pump to supply line and dropped it into the tank. Fill up all the tubes perlite. Turn the pump on and began looking for leaks. Almost ran the tank dry before any water started returning to the tank. Did not realize how much water the perlite would retain. In this case, about 8 gallons water. Added another 6 gallons of water to the tank. No leaks were found. Will be putting strawberries plants in this Saturday.
