Anyone ever have problems with them in an Anemone tank? I Was going to try them with Foam or mesh around the intake area.
Eductor nozzle in Anemone tank?

I haven't, but I am also thinking about doing this. It seems like wrapping something over the intake would decrease the suction, and possibly defeat the purpose of the eductor. But I'm no physicist.
Just worried about anemone getting sucked into it.

I have two of them for the returns on my 150 and haven't had an issue.....yet(knocks on wood). However I do have all the rock 6-9 inches away from the sides of the tank since I have a H. Magnifica in there. I can post some pictures later if you would like i just have to upload them to the computer.

While you say you're not a physicist, it seems as you have a firm grasp of the technology. They basically work very similar to the venturi valve on skimmers. Fast moving liquid flowing past a slow moving liquid creates a negative pressure area, pulling the slow moving liquid into the fast. (still with me?). Now you have - for almost free - more flow. The speed will slow down slightly due to conservation of energy, but the volumetric flow rate will actually increase a little bit.
By putting a gaurd around the intake of the eductor, it would be like putting foam in the air intake to your skimmer, thereby greatly reducing effectiveness.
The biggest danger to anemones getting sucked into pumps is the fast spinning impeller chopping up the nem. Since the eductor has no moving parts, the only danger is the nem in so high of a flow area that the water causes damage.
