powerhead placement?

[hoyt]

I just upgraded to a 90 gallon all glass with a built in overflow, I have a rio2800 as my return pump, I have a hagen 820 and a rio 2100 as powerheads, how should I position these to get my best flow? Are these 3 going to provide adequete flow in my tank?, thanks for the input

Your rock placement will determine if you have the right amount of flow.With so many types of rock available what works in one tank may not be enough in another.

It all depends on what you have in your tank or what you plan on having. I would experiment with the PH placement and positioning to get flow to all areas of the tank. You can then re-evaluate if you need more flow or just better placement.

There perfect location. Try them in one location for a while and move them as necessary. The only trick is to try to diffuse the flow as much as possible to simulate ocean current. One good way is to just aim the powerheads at the glass.
