Best powerhead to use

Just looking for opions for a powerhead i should consider for my 29 gal biocube. It looks like i have a couple dead spots where the color on my rock is disapearing. I know it will come back once i get more flow in the tank so the debris cant settle on it. What are the good ones and the ones i should stay away from? And where should i place it?

 

koralia 1's? for a 29, not sure but I know they're really good back or side of tank facing front but at an angle

 

Korallia 1 would be perfect in a biocube29. got a korallia 1 and a korallia nano in a RSM

 

+2 on the koralias, I have some and they are awsome.

 

id go with a couple koralia nano's and maybe a koralia 1 or 2. its better to have more small powerheads moving water in a chaotic motion than one large powerhead just blasting one area which will cause the water to start moving in a defined stream.

 

Id go with 2 Koralia 1's. Where you set them really depends on too many factors to tell (the arrangement of your rock/decorations, where exactly the dead spots are, etc), it will be something you will have to play with. General rule of thumb for water flow is you want AT LEAST 20X turnover rate, wich means for your 29 you want a total flow of 580GPH, and thats kind of a bare minimum. 2 Koralia 1's would put you at 800gph, which would be good. I paid like $38 bucks for a brand new pair of 1's, so its a cheap upgrade that will make your tank inhabitants a lot happier;D

 

I'm with PL. 2 Koralia 1s. eBay is the place to get them. Very inexpensive.

The link John provided is actually the exact seller I got mine from. Transaction went perfectly, and he shipped them very quickly. If your looking to get the pair of 1's, I'd jump on it

 

I bought a #3 and #4 and I love them such great flow in the tank, I ordered from this website they have a sale going on till the 15th, cheapest you will find right now, and quick shipping and so forth. I saved about $30-40 bucks on my two.

You could, as That Guy stated, add more smaller powerheads. A nano in the back faced forward would create more waves, and it's only adding 240GPH.
