Return pump recommendations

[Marcom12]

setting up a 75 Gal tank with a 30 Gal sump.... what size pump should i get? or need?

 

[top shelf]

Head hight, turnover rate, and what size plumbing you intend to use dictate the size pump you need. Will this sump be in the basement what 10-15ft of head pressure? Will it be in the stand under the tank? What size plumbing is being used?

beyond any discussion, is fundamental that the exchange between the sump and tank is more to the water treated by the skimmer

if I wrote bad it is Google's fault ^_^

Its a 75g. So lets assume you are putting the sump under the tank in a stand. 90% chance of being correct. 3/4 or 1" plumbing for drains and returns. Maybe a charcoal and another reactor down the line. At min you can prob "get away" with something like a Sicce Syncra pump 5.5 (1400 gph). In my opinion its a bit small but might work. Maybe not with adding reactors. A better option would be Sicce Syncra 7 (1900gph) or a 9 (2500gph). This way you wont have to worry about an under powered pump. There are many choices.

I have a deep blue 74 gallon tower for my new build.. just a little 10 gallon sump for now.. I plan on adding a 10 gallon fuge as well..
Anyways I have a jebao dct 4000 return pump.. 1 inch drain... 3/4 return
Simplicity 120 skimmer..

I've got the return pump set on the second or third lowest setting and it seems to be about perfect for me..

The tank is a tower tank so the glass is 31 inches tall and the stand 32 inches .. giving me 64 inches of head height (return ford an inch or so above the top of tank..
I have no idea how to figure out the gallons per hour though

Well .... Maybe i should add that this is my first tank so i dont know alot of the answers to the first response.

head height is approx 5 ft. sump will be under tank. size of plumbing is...3/4 i guess. i suppose i can make it whatever is needed or best.
and no idea how to determine turnover rate.

The tank came with a "reef ready Plumbing kit" i understand i need to supply my own plumbing between tank and sump though.

If your 75 came as mine did with corner overflow and 2 pre drilled holes you might want to consider a herbie setup which will utilize both pre drilled holes as drains, one being the main drain and one becoming an emergency drain.
Then you can run your return line up and over the top of the opposite corner.

This link will give you an idea. Make sure to put a valve in the return line so you can slow the flow down if needed. I'm pretty sure I have the 1262 with about 7ft of head with the rise and fittings and 1" pipe. I had to slow it down for the overflow and skimmer. I am also running a dual reactor off return the line too.

Excellent link for herbie setup, if you're interested.

Do i need a pump that big? im not questioning you ... well kinda, but not in a bad way.... im just trying to figure out the "Whys" for things

im assuming if i have 5ft head pressure.... i dont want a 5 ft max head pressure pump..... i want something say..... 25% or 50% more.... so i get the full flow? or something?

You want a pump that will return XXX gallons per hour at your XX head. many pumps will display a return curve either on the box or somewhere "out there".

On top of this I'd suggest something with a bit of a track record for reliability -

some pumps are quieter than others - something to keep in mind with an under the tank setup.

I prefer a lower XXX gallons per hour.

Lastly you can put a valve on the return line to adjust the flow without harming the pump.

i guess i didn't realize how complicated this seems to be. I figured for a 75 gal tank and a 30 gal sump there would be some "standard" size. or at least a window of options..

Unfortunatly im not sure what gallons an hour i need or want... nor am i familiar with how to determine it. i dont mind doing research but i figured it was a simple question.

Sure, a simple window would be 300 to 600 gallons per hour at 5 foot of head.

I like it to be on the slower side of the window. It'll make it quieter.

ok thank you . and i dont want a pump with 5 ft of head right?

Most pumps will have a chart of flow at various height. Obvously 0 at 5 feet won't work for you. Most pumps the size your looking at will handle 10 to 15 feet of head and at 5 feet I would look for something in the 300 to 400 gph range. Probably a pump with a 0 head rating of 700 to 1000 gph.

Get a Jebao DCP 6500 and call it a day. No need to over complicate things. This return pump is a dc pump and comes with a controller so that you can adjust the flow as you need. This is what I have on my 75. Done.
