    Is the ReeFlo Barracuda/Hammerhead Hybrid 6000/4590GPH pump submersible (in-sump) or not-submersible (external) or both?

    Bulk Reef Supply Hi Shawn,
    All of the Reeflo pumps are external pumps, they are not submersible.

    Setting up my first saltwater tank looking at 48 inch 120 gal. on the main floor. 36 gal sump in the basement, head pressure will be about 15 ft. Need help with GPM. This ReeFlo Barracuda/Hammerhead Hybrid sounds like the right pump. Is this over kill? If so what GPM should I be looking at? Starting as a FOWLR then looking for some corals.

    Bulk Reef Supply Hey Curtis,
    Below is a link to the head pressure chart. It sounds like this is likely your best bet but the GPH will vary depending on what impeller you have in. With the Barracuda impeller in @ 15ft of head pressure you can expect around 2400gph or so which should be plenty good. If its a bit much you can always turn it down a tad but as a whole, for a pump capable of pumping that type of head pressure pretty good choice.

  • Excellent/Efficient Pump By Tharon on 1/23/2015

    I purchased this pump as the work horse for my reef system- two 90 gal tanks with remote sump/refugium. With approx. 10 ft head pressure and 10 ft distance from tanks, this pump handles it with ease. I actually had to dial down the flow using ball valves as the pump was too powerful. Very quiet, very efficient. Highly recommended.
  • Quiet but seem to be not as strong as the original barracuda By Captain Greg on 1/22/2015

    I like the quiet. Head pressure is questionable. Most user don't use the pump to push water through large amount of media like I do. Regular water lifting is good for this pump.
  • Awesome By mackjr1969 on 11/14/2014

    This pump is like the description says! Pumps quiet and a beast!
  • awesome pump By dominick on 11/13/2014

    I purchased this pump to run my 220 it is in my basement pump water up about 10ft,plus have it running a.big skimmer,a reactor and still have it dialed down a little bit very little noise highly reccomend this pump for big setups
  • Very Loud By Michael on 10/29/2014

    I purchased this pump about a month ago and finally got it setup yesterday. It is so loud that I hear it in my living room, even though the pump is in the basement on one of my sumps. Decided to buy another Dart Hybrid instead and sell this one on RC. Not worth it unless the noise isnt an issue.
  • Excellent flow even with higher head pressure By Jill on 10/5/2014

    I installed this pump to return from the basement to the 220 main floor tank. Plenty of flow and quieter than other pumps we have used for the same application. We had no issues swapping impellers. Just make sure you have the right wrenches.
  • Not so easy By TZ on 4/6/2014

    Removal of the hammerhead impeller & replacement with the Barracuda impeller was impossible. Fortunately Chris at Reflo replaced the entire pump for me. It's not as easy as they might suggest to change impellers. Otherwise, a good pump.
  • Works great. By Sammy on 3/13/2014

    I've been running this pump for 2yrs on my setup. Relatively quiet, though not super quiet. Plenty of flow though!
  • Very Nice Pump By Bill on 3/8/2014

    I have installed this pump to supply a header unit to feed my systems - replacing several smaller pumps. Works great and reduced energy use.
  • can't beat the price and quality of this pump By Michael on 1/8/2014

    I hate to spend money twice on trying out products, reeflo had never failed me, two years now and its still running strong, its quiet for its size, I use this to pump my sump from basement all to the way to my main floor, that's over 20' height (big house). I like it so much I even bought another one just in case, but its been two years continuously running, no issues at all.
  • Great pump By Dustin on 11/21/2013

    I have had this pump on my 300 gallon for over 2 years now with no problems and works perfect. i think its pretty quiet considering the size.
  • Great water flow and very quiet! By Jason on 11/16/2013

    I ordered this replacement pump for my 500g tank. It replaced a earlier version of the hammerhead. The new model is much quieter and runs cooler than the older version. I also like that you now get two heads if you don't need the flow of the hammerhead.
