I have a total of 28 3gal buckets running that size water pumps.

thanks for breakin it down for me:thumbsup:
i was just reading throught the CAP ebb & gro instructions (pdf) and i was looking through the parts needed and everything is based on 1/2" tubing and connectors. I was going to use the 3/4" tubing and fittings. Anything wrong with that? i figured if i was using bigger buckets (5gal) it wouldnt hurt to use bigger lines and fittings. Anyway i noticed on the parts list i noticed they included 90 degree elbow fittings for the controller bucket feed line that have a hole in it to break the vacuum seal in the tube....
ive been googling for the past 20 minutes and i cannot find the part they have. could anyone supply me with a link to find this particular part? Maybe i dont even need it? could i just punch a hole in the tubing about an inch above the water level and it have the same effect? or would this create too many air bubbles in the water lines?

sorry for the million and a half questions lol im totally new to hydro and i just wanna do it right:rastasmoke:
