Last night I did a quick mod to my power head. I took the air intake tube and moved it so it's all underwater. I took a medicin port off of an I.V. line and glued it to the end of the air tube. The tube is now filled with water, but I can inject pulverized food, in tiny amounts directly into the stream of water. My newly aquired bamboo shrimp love it. They pirch on a shaft of dirft wood and filter away.
FYI, the tank is filtered by a HOB biowheel filter, so the power head is just moving water around.
