The answer to your question lies in the size of air tubing you plan to use. I would recommend 1/2" ID to at least a two way valved manifold (you can make this with pvc and 1/2" ball valves. Then reduce the size coming from the open end of the ball valves to 3/8". You can use the grey thread/barb fittings to change your ID needs from 1/2" to 3/8". then attach 3/8" ID tubing to your diffusers. Just add one diffuser besides your BD so you can regulate the air. Also, in case the BD isn't enough air flow, it won't put too much back pressure on your pump. 5' deep 15 feet away should NOT be a problem for this pump!
