How strong of a return pump do I need?

[elmotheodd]

I have been doing a lot of reading on this but haven't found a solid answer yet. I believe my overflow is an eshopps 800 and I'll be using a 10 gallon sump how strong of a return pump do I need at about 4 ft head ?

Depends on your sump needs. Some are low flow some are high flow. Are you doing the typical 3 chamber sump (Skimmer, Fuge, then return)?

The sump is 2 chamber mostly refugium. I have a Hob skimmer because of space that ill be using on the sump

Rule of thumb is no more than 10x your display tank gph. So you fill have to add that on top of head pressure to come up with the amount of gph pump you need.

I shoot for 5-6x the tank size of actual flow. This will mean a bigger pump with head losses. I don't like high sump turnover.

 

[elmotheodd]

So 10x I'm.looking at 460 gph pump with 0 head so if I went this correction I would need like a 600 gph pump to account for head loss?
Or would it be ok to just get a300 gph pump for 5x turn over? Would I want more or less flute in the sump

Id shoot for a 400-500 gph pump. That will get you 300-400 gph after head loss. The 300 will be too low and youll get bubble formation in your overflow if its external. If its internal, a 300 gph pump is perfect for a fuge with no skimmer.

Awesome thank you everyone for your help!

Ive had good luck with long term reliability with the mag series. A mag 3 or mag 5 would work well for your needs.

I personally don't like the mag pumps, too much heat added to the tank (great during winter, not great during the summer with an anti-A/C BnC). Impellers are an issue for me as well, they seem to break on my systems.

ReefCentral has a head pump applet for download on their homepage.

Hmmm what pumps do you use/suggest?

I like my Sicce Syncra pumps...

The Sicce Syncra Silent 2.0 Multifunction Aquarium Pump would put you at 568 GPH.

I have a sicce syncra 2.0 Im not using, if you want to try or buy. It was my return pump before i changed to a basment sump.

 

[elmotheodd]

How many gph and price ?

Didn't mean to discourage you from them, jda seems to like them (have you seen his tanks?).

 

[elmotheodd]

Oh no worries I'm taking in all the information I can get... added heat could be an issue setting as I try not to run the a/c but that could be changed lol

[elmotheodd]

And no.I haven't had the opportunity to see his tanks are they crazy cool? ( like any saltwater tank isnt lol)

Is it plausible to run an external pump on a sump.That isn't drilled?
