i don't have any plans to give you but i believe geoff has something .
the best advice i can give you is make sure you get a strong
pressure rated pump to drive it . even if you have to put a tee on the pump to devirt some of the pumps flow , it will make it easier to get the skimmer to do what you want it to do .
you will not need to add a second beckett to the size you are planning on building , one with a good high pressure pump will work wonders .
for a comparision , i built mine with 8" tube , its just under 4' tall and has no reduced neck . to run it i'm using a little giant te 5.5 rated at 2150 gph at 5' . i switched it over to 240 volts to try and make it more efficeint , and some of the bleed off runs my chiller .here is a pic of the skimmer body .
