Hydor Koralia 4 - 1200GPH

[Zoous]

Anyone using this product? Is the flow rate adjustable?

Nope

 

[Deanos]

I use a Seio multicontroller to reduce to flow rate on my (2) Koralia 4s. It reduces the output 50% for a user set timeframe (15s minimum - 30 min maximum).

Deanos, Do you know if anybody has tested the controller on lesser Koralia models?

 

[Deanos]

I tried it on a Koralia 3...it didn't work. The pump rattled when the power changed.

Hi Deanos:

Are you saying you can't adjust them without a controller? Also do you think the 1200gph is that too much for a 50 gal?

How do you like them?

Thank you.

 

[Deanos]

They are unadjustable without a controller.

I have (2) Koralia 4s in my 65g.

I love them :flirt:

Can a fish get caught inside and get killed? Also where is the best place to get them price wise?

Thank you.

My blenny once got stuck on the outside of it but he's nosy so he gets himself in a lot of trouble. But I wouldnt think that any healthy fish could get caught on it, fish are strong enough swimmers that they would be able to swim against the draw of the koralia. My sailfin loves it and a good place to purchase is championlighting . com and the last time I went to New world aquarium about 2 weeks ago they had some also but NW is pricey.
