Seek Advices - Sizing of Pumps

[dorje]

Hi There,

I have this tank size - 4.5' x 2' x 2.5' ht, the total volume is about 573 Litres (based on 90% full water level)

I saw some threads in other forums, stating that a norm is to be able to turnover 3 to 4x the total volume of the tank. Thus for my this 4.5' tank, based on below which Pump should i go for? (am using over and underflow - internal filtration systems)

1. 573Litres x 2.5times = 1433 L/H (is it too weak to push waste in maintain?)

2. 573Litres x 3times = 1720 L/H

3. 573Litres x 3.5times = 2006 L/H (get a 2000L/H - good enough?)

4. 573Litres x 4times = 2293 L/H

Rating of Pumps

OR3500 - 3500 L/H (over powerful - is the flow rate too fast for BB cultivation?)?

Aquabee3000 - 3000 L/H (ok?)

Eheim1260 - 2400 L/H (ok?)

Sicce Multi 2500 - 2500 L/H (too weak?)

RIO 14HF - 3190 L/H (ok?)

Any other recommendations from you?

IMHO, at least 10X and above .

I'm using 5800H/L for my 3 ft tank, 300L and i prefer 20X flow rate .

Even those, you still have to cal in the height from the pump to main tank, L/T joint....It will reduce you flow rate if too many joint involved.

yup i have 4x2x2.5 too i using two ehiem 1264 cheers my 2 cents

agree with james and clowny,10x above will be ideal..

why not get aqua bee 7000.. but make sure ur overflow can cope.

hello bros,

just to check if this 10x rating also apply to fresh water aquarium?

sorry ,not very sure with freshwater setups.
