flow assistance

[Laybck reef]

hello everyone new to the forum, i have a question that could have already been answered,

i have a red sea reef tank 350, 90 gallon with two red sea wave 45s in it hanging vertical on the back wall is this going to cause enough flow or am i better of running them horizontal on the back wall or side glass.
i would like to keep them on the back wall to keep the viewing area nice and clear.

Depends on a lot of factors, such as your scape (rock placement) as well as what you want to keep and where you'll be placing it on your scape. Also depends which mode you run your pump in and strength.
Best thing to do is set everything up and then let the pumps run and watch the flow pattern and adjust as necessary.
