I'm currently setting up an ATO and about to build something to house and hang my led kits... I really want to try at diy version of that german rain system. I am in a great position to experiment.. I'm single, live alone, and have funds... I also have a neptune controller, AI leds that have the lightning storm, vortech pumps that could switch too, and an open top tank!. Soo..... Besides the normal float switches, all I need is a stronger pump (to over come the 5-5.5 feet vertical and 4-5 90s) and then how / what would I use to create the rain effect? I'm thinking I could us a pvc with a T and run from the middle and down each way on the inside front of my light enclosure. Drill holes along the bottom and close the ends. Backup will just slow the pump down... Or am I missing something.
