The only reason I asked about the pump was because of price. I am on a budget and anywhere around her that i live they want way to much for the systems that I want to use. So I wanted to down size the set up and use smaller pumps. I downsized from 14 spray head to i think it was 10. They suggested a 350 GPH pump. seeing as i downsized. I was wondering if the 250 would work. I need 7 pumps so that price tag get up there ya know.
