I need help everyone. I recently switched over to HTG Supply's Big Boy Ebb and Flow system. It has twelve 3.5 gallon sites using a 55 gallon reservoir. I wanted to know what is the most effective fill and drain settings and once it fills the sites, how long should I allow it to sit before draining. I use digital timers that are in sync so just let me know what you guys think and I will appreciate it.
