I believe this pump does around 700 at 1ft head and can push 10ft at around 500. would probably do better as a skimmer pump. i just want a internal one that is around about 600-650 at 4ft head.
This is what I found on Amizon.
2400 gallons per hour (gph) magnet drive pump with 19 feet maximum lift (head). Uses 240 watts of electricity. The inlet is 1" female national pipe thread (FNPT) and the outlet is 1" male national pipe thread (MNPT). The outlet also accepts 1-1/4" ID flexible tubing. Includes non-clogging pre-filter as shown to protect the pump from debris. Equipped with 18ft power cord for use in ponds. Energy efficient - low electrical consumption for the high volume of water being circulated. Fish safe epoxy encapsulated motor - no oil to leak out. Only one moving part - no motor seals to wear out.
I don't have the the pre-filter because I was busing as an external pump until recently.
I think after head they are fairly close to the same at 4 ft. You can also use a ball valve to slow it down a bit if needed. That is what I have to do right now using it on the closed loop. I think that your pump would do better as my closed loop pump then this mag.
CONGRATS! yea no rush at all take your time.....and i would probably leave out the fish club update. Boy or girl?? how big? I love it when they are so small mine is growing so fast!
