My current pump that I use in my sump is a Rio 4600. I've had it almost two years and have replaced the impellar once. This thing is so loud that it's ridiculous. I believe its because it can't handle the straight up head of about 8 feet that the water needs to travel to get back in my aquarium (225 gal.) If I run it in a bucket with no back pressure on it, it's silent.
I've been looking at Home Depot and Lowes for pumps, the larger ones seem about the right size but aren't useful for saltwater. Does anyone have any experience and reccomendations for a pump that can handle a 225 with 8' head and is relatively quiet? I know it's a lot to ask of a pump, but I need to ditch this Rio for a more reliable and better pump.
Thanks :)
 
Reefs.org has an excellent article comparing different pumps. Since you know your head and how many gph you need, you should be able to find a few pumps that will meet your needs.

Avoid Rio like a PLAGUE.. Too many people have wiped out entire tanks with those things.. Too risky, IMHO..
 
I've been using Danner mag drives for years. Cheap, reliable, relatively quiet, but have a slight tendency to leak when used as external pumps. Adequate, but there are better pumps on the market.
 
Thanks Mog. how much of a turnover can I realistically get and what should I be looking for? I'm not having much luck finding pumps that get much more than 1000-1200 gph at about 8' head. Is this enough turnover for a 225?

Actually I see Danner Supreme Mag-Drive pumps on Ebay that can do 3600 at 1' head. You say these leak? What do they leak, it looks submersible?

For an external pump, you cant beat the "sequence" pumps. They are pricey though. Remember when you are using a submersible pump like mag drives, you are puting a heater in your tank as they get pretty warm.
