Powerheads

[Willba200]

Ow many power heads would you have in this tank??

 

[Willba200]

33g 149l tank. Gonna have corals etc.....

The more powerheads the better but shoot for flow between 660g /2500l and 1320g / 5000l per hour in flow.

 

[Willba200]

Looking at my tank..... What would you go with???

 

[Mebbid]

What are the dimensions of it?

 

[Willba200]

3ft long w 13" height17"

 

[Willba200]

Give me a DUMMYS answer ..... As in smaller pointing towards surface, lager on the rock??

 

[Willba200]

Very new too this as you can tell.

 

[Willba200]

I was thinking that I need flow at the top to create movement and flow for corals?

 

[Airgoose2222]

Recommendations for FOWLR tanks is ten times the number of gallons for flow. Corals is twenty. Double check that, but that's what I recall others saying on various posts. Those are usually minimum flow rates.

Getting water flow correct is probably the most difficult part of setting up a reef tank. 3 different powerheads would give you quite a bit of different flow options so I would shoot for:

1 of these
Hydor Koralia Evolution Pump - 600

and 2 of these
Hydor Koralia Nano Pump - 425


Positioning them will be 100% dependent on your scape so you will have to play around with it for a few weeks to get it right. I would position one angled upwards creating surface agitation and the other two can be angled in different directions.

I would go with a Hydor Koralia Evolution Pump - 850 and two 600s, but I like current because the more things move the less they settle in the wrong place.

That's 60x the tank volume... that's getting excessive

One Jebao WP-25 would be enough if not too much.

i have that tank as a fowlr and i have a pair of hydor koralia 425s flowing directly at eachother along the bow of the tank about 2/3 the way up on each side.
