  To start, make four lines equidistant apart along the side of the pipe. These will be about 3 1/2" apart and should divide into quarters. Next, make seven points along each line spaced 5" apart vertically. At this point, it's time to drill the holes. If your reservoir bin allows for more space, you could add additional rows. The spade bit is exactly the same diameter as the outside of the PVC elbows, so I had to rock the drill side to side in order to widen the holes for the elbows. Once all the holes are drilled, you can put silicone around the elbow and press-fit them into the holes. You can also scrape the excess silicone off with a little spade. The pump I used was too big to fit in the pipe, so I had to also drill holes around the bottom to feed the water tube through and to let the water recycle back into the reservoir.
