I have a Tiger Goby and he stirs up a mess everyday. My SPS has full PE the entire day and has good color and great growth.
I wouldn't worry about a power flush situation or having stuff suspended in the water.
Also, I love your fish room, and your DIY abilities. I wish I had the time and money to tinker with stuff like this.
