....I am wondering what a safe distance from the water surface or sandbed is to prevent sucking air or sand at your suggested flow rates for the 3/4 nozzle.

I have never tested distance for the sand bed, but I would assume it similar tp the the water surface - so if you keep it 3/4in to 1in from sand bead (or three surface') then you should be good.

Here's quickstart guide to your you started in terms of how best to position

Great, thanks. Then my idea should be worth a try.
