Good thing you don't have to worry about the likes of her here anymore. I'm surprised you manage to keep your composure as well as you do with the inane crap/invective thrown your way. It's not good enough that you settled the peace between the tubing size, but they feel as if you didn't go far enough, hoping for a proclamation from you of "Low flow is the only way to go!"

As for 12v or 24v pumps in the 8-10gpm mark, your choices are very limited. Best to first identify how much back-pressure we're expecting to operate against at that level, and then we can construct a solution for the problem. It is unlikely that there's a single pump that will do what you want, but a pair of pumps, such as 2 x Iwaki RD30's in parallel would get you pretty close. I'm not really aware of any stronger DC pumps than the RD30's that are easily available to the general consumer.
Why two RD-30's in parallel rather than series? I always figured series was the way to go.
