I'm planning on getting an anemone sometime in the foreseeable future and had read that they are notorious for getting into wave makers. I tried looking into something I can use for my tunze 6105 but didnt really have much luck other than using some sponge tied around the vents, which I may have to end up doing, but I was wondering since my wave makers are mounted high if the mesh is even needed? Here a pic for reference. My tank is 24 inch high and tried to keep rock work around half or less under pumps
