How much water flow?

[drm180]

I was thinking about ordering this powerhead. Hydor Koralia Circulation Pump/Powerhead UL
It's a Hydor Koralia. I was wondering which size to get. The second size is 600 gph. I currently have one 170 gph penguin powerhead blowing on my rock, and a maxi-jet 1200 with 295 gph running my skimmer. Is the 600 gph too much?

In a 10 gallon,just get the #1.

This is a 25 gallon. Sorry, I forgot to mention that and I plan on keeping soft and LPS corals later.

A number 2 should be plenty.

I don't like the Koralias. They stick out into the center of the tank and are unsightly. Get a smaller (and less expensive) 20G power head and put it in the back corner. It will do the job just as good.

The Koralia 1 is plenty for a 25G. A Koralia 2 will be too much. If you get a powerhead, get one rated for a 20 or 30G tank.

I've got a koralia 1 in my small tank and it's not that much flow at all especially if it's pointed at a rock it loses all it's energy. I have to have mine pointed at the glass for adequate flow otherwise watchout cyano. I'd suggest getting either 2 #1's or a #2.

Do you have a better suggestion for a brand of powerhead? My tank is starting to look rather cluttered now and I'd rather not add anything big if I don't have to.

seio makes a nice one for small tanks

 

[drm180]

What size would you recommend? The 620 gph?

 

[daugherty]

yea i would do the 620 one for a 29

All powerheads are unsightly and the Koralias aren't anymore/or less than the others.
