Now take the spider and put 4 of the 8 tubes in it so that they form a cross. Then Put it up under the existing one and loosly zip tie it into place ( you are going to cut it down in a minute). Next you need to cut the distribution tubes to length such that they will empty out into the trough. (I had to offset the center of the second spider slightly so each tube is a different length) Measure the distance you need then pull the tube out of the spider and cut it down. then re- insert it. Repeat this on all 4 sides.
