I've not decided between 2 options:

(1) The maximum possible flow tolerated by the corals, to basically eliminate the static barrier layer (analagous to insulation) of water around the surface of each coral, to maximize diffusion from the coral to the tank water and vice versa.

(2) Enough flow so that every SPS coral everywhere in the tank gets some flow. Ie. there may be excessive flow in some areas of the tank, to ensure that there are no "dead" areas or areas of low flow.

I am doing option (1) but have had edges of some corals killed when too near a powerhead. I have a feeling option (2) is correct, which is why the Maxspect gyre seems interesting - it would ensure flow everywhere in the tank without excessive flow in any one area.

The other option I thought about was just brief periods of very high flow, such as a minute of high flow every 15 minutes, might experiment with that.
