pump info for a friend

[sea gnome]

He will be using a protien skimmer like the one I made but a little bit smaller so it will fit inside he sump. Brad knows the size so you're right that there probably won't be the necessary pressure with just one. Hadn't thought about that.
There is a place in Victoria that sells new/used pumps and we got one for our pool a couple years ago. It has a 1hp motor and I was also thinking somthing like that might work if the noise wasn't a huge factor. any thoughts?? Rachel
