I have 2 4x4 flood tables and two 30gallon res. The guy at the hydro store told me that 30gal. res. was enough to fill the table and when I ran the pump it only filled up to half way up the table and the pump started to run dry. So im guessing I need a bigger res. Also, it takes about 5min to fill up the table half way.. and 10-15min to drain. Is thier timers that turn on for 5min. and off for several hours?? I have a 3on/off timer but It cant be turned on for less than 30min. So what timer should I use?? THanx for reading
