I use a quiet one 3000 . what I do is remove water, then start up return pump quiet one 4000 and my 3000 with no head can keep up and that's how I refill my system.
Thanks for all the replies and ideas. You know, I didn't get notification of most of them till I looked at the thread this morning to refresh my memory.
I'm leaning to a mag 7 or 9.5. They're on sale at Dr. F&S.
What do you think, Donnie, a mag 7 or mag 9? It's for mixing salt water and pumping back into the tank. Also I wonder if I could pump the sump out with it. I used my maxijet for that but it kept stopping it up. I've looked on the board and found one used one, but I have a credit at Dr. F&S that I could use up.
I use a mag 7 for both mixing and pumping the new water into the tank. The return pump (Dart) on the sump takes out the old waer. I can do a 35 gal water change in about 7 min.
i just use a quietone 1200, while its not incredible fast, its nice and small and easy to work with.
bought 2 actually, one for mix and filling the tank back up with. the other for misc stuff and draining so i dont have to worry about cleaning in between or anything i dont want in new water getting there.
