recommended return pump flow rate

[Rex Ng]

any recommended flow rate of a return pump for a 4 x 2 x 2.5 HT

[Lester]

hmmm i think it is something like that

cal ur total water volume i ur tank.. then see you wan how many time turn over.. and size ur return pump..

i think normally is 8x, but some goes to the extend of 12x i believe..

hopes it helps

cheers

i went for >30 times.

ur skimmer turnover rate plays a big part too. u will wanna fully utilise the capabilities of ur skimmer.

no point getting a return pump 12x that the vol of ur tank but skimmer pump driving 30x right?

work on this calculation to estimate the F.R. of pump. hopes this helps. very much depends on what are the turnover you prefers.

30 times! That is a lot. Can share with us what is the configuration you are using? I was planning 20x for my 4 feet set up and end up requiring about 12000 lph pump. Too ex for me so I have to settle for less.

total true water vol of my reef = approx 200L

return: RD 6500

skimmer: Iwaki MD55R5, 70L/min

Ooooo... Red Dragon... beyond my budget.

any recommended flow rate of a return pump for a 4 x 2 x 2.5 HT

Go for Quiet one 6000 = 5800L/hour at 100W.

Affordable and performs as good as OR6500.

I have been running it for my 3.5x2x2.5 for 10 months.

So far so good. Output very storng.

Best if you can use 2 of them and 1 of the pump T-off to chiller then to main.

sorry hijack abit. How abt resun MD55? I am running it and still do not know wht's the flow rate like and energy consumed? sounds stupid but.... still need to ask around.....

THought of changing to Quiet One, where can I source for it? anyone knows the place and px?

Sorry off topic.....

Bro Lightingstrike,

Wah you use MD55R5

That is 170W le.

Might as well use MX70 to push ?

That is 130W may be more for 3600 l/hour.

It is a waste to run pressure rated pump for return.

Quiet One available at many shops.

Petmart, Ocean planet and many more.

If you go for real Iwaki, they have pumps specialse for return.

MD40RX => 85W for 4500L/hour.

[xpert1974]

Thanks Sugi

but the thought of changing to another new external pump, the process itself really daunts me. I am really afraid of flooding the whole floor......

If my tank is 4x2x2; The height from SUMP to Main Tank is est 4ft. What Return pump should I used?

Thinking of:

1. TOM800 - 800G/hr - $50

2. Eheim 1626 - 4000L/hr - $200

3. SICCE 4000 - 4000/L/hr - $100

Which do you think I should get?

MX70 is juz a tinge 2 powerful for my usage, thus i chose to go with MD55R5.

Klim,

My return pump need to pump up almost 2 meter height.

The output still very strong after head loss.

I have considered various affordable pump and study the head loss graph.

I still find Q1 the best.

ur Q1 uses it in insump or outsump? if you use it for outsump, does it produces noise?

[sugi]

Loster,

It is almost silent.

I put a wood plank cushioned by styrefoam.

2 Q1 pumps siting side by side and the vibration absorb well so not much noise.

[lightningstrike]

wa.. RD.. you must be rich man. .. wan god son

wld u rather buy a pump that is not up to ur expectations and keep on upgrading?

or wld u rather settle for the pump which u think it is the best out in the market and not lose sleep over it........

it's not a case of being poor or rich....... but IMHO, affordability vs reliability.

btw, what's "wan god son"?

[klim]

Loster,

2 Q1 pumps siting side by side and the vibration absorb well so not much noise.

So Q1 - what's the pump rate you used?

[loster]

hmm...might want to go for higher flow rate... i did consider Q1 cos it is slightly cheaper than OR

that's interesting and good idea using wood plank cushioned by styrefoam

my eheim 1262 gave that "vibration" on the base

get some rubber dampers and fix to the bottom of the 1262.

He meant if you are looking for a god son... So that he can acknowledge you as one.

You have a point. But forking out a few hundred dollars for a pump is not something that most people would consider.

[hotlemond]

but if you have stock up hundreds of dollars in the display tank, a reliable pump does make sense.
