Improving Circulation

[jrussuk]

Hi all.
I,m looking to improve the circulation in my 90ltr tank and was looking at the Hydor Koralia Nano Power Head. I was worried at its output was 900 ltr. Can anybody recommend this powerhead or if its too powerful any other makes as this one is the smallest one i can find.
Many Thanks

If it truly delivers the 10x flow, it is too big for most situations. Have you looked at the other brands of power heads that are available? I have several different size AC power heads that provide nice controlled flows lower than 900 l/h.

The koralias are great pumps for marine, however if you just want a little extra flow around your trop tank, look at maxi jet they do the job and are quite cheap. Or get another filter gives you a back up in case one fails, increases your flow and gives you more room for different media,
