29g BioCube Power heads?

I have a 29g biocube and was wondering if it is recommended to put any extra pumps on the glass or back for more flow? All I have is the one in the sump that just pumps the water back in... suggestions?

 

I have 2 of the Korlia 425s and the corals love it

 

one on each side?

 

One on back and one on side. But both sides would work. Nice little pumps

 

I have one koralia pump on my 29 cube. If you keep the return pump clean one pump will be more then enough. Pump in the back chamber kicks out a lot of flow. So one pump is almost overkill when my pump is cleaned. Just my 2 cents.

 

Forgot to mention mine is in the left side glass so that it pushed the flow in the same direction as the return.

 

FLow depends on the corals you want in your biocube. I've got a 34gal Red Sea Max. In addition to the two return flow pumps, I've got an MP10 that is cranked up about 60-70%
