Hello, when you dump your pods in the tank or fuge don't just dump them in the water. Get a clear plastic tube about 1 inch in diameter and long enough to reach down to the bottom, place the tube into the rock structure and pour the pods into the tube and give them time to settle in the rocks, pour tank water into the tube to flush any pods left over. Do this with all your pods in several areas of the tank. I turn my flow off for a few minutes also. If you dump them in the water column they might get filtered out. I think it may benefit the pods survival.
