OK then I guess I have strong flow, even though the polyps on my sps are bearely moving. I had no idea that was still strong flow.
I though to qualify as strong flow, the polyps had to move more than this. As it is, they occasionaly move, from time to time.
Here is a full tank shot. Does that quality as good flow?

If you switched to a single small aquaclear, you would notice the thing growth that we've discussed.
