Flow on my Bow

[Beachbilly]

I got two 420gpm on my 29" tall in the back flanking both sides pointing upwards angled towards the front and one more 420 in the middle left with two hanging filters. Is this enough flow for coral? Any suggestions on better positioning?

I see a flat water surface, you should point one of the powerheads towards the surface to help with gas exchange and help oxygenate the water.

Its very hard to judge the flow based on a pic. The best way is to put an airstone in your tank and watch where the bubbles flow, this will help you position your powerheads in a way to avoid dead flow spots.

I appreciate the feedback, fist I heard of the airstone, I will try that also.
