Bubble tip anenome vs powerhead

[Gallivanting1]

I added a bubble tip anenome to my tank on Wed and all was good. I went out on Fri and came home 3 hours later to find threads of him coming out of the powerhead. I guess this is common but I read that you could but a stocking or netting over the powerhead and cut a hole out so the water can flow out. This is a temporary measure until the anenome finds a home and settles in. Has anyone tried this? I don't think it would be very good in the long run because of the restriction to the intake flow. Thoughts? Also, I'm not getting another as I picked up a really nice rock flower anemone who likes the bottom of the tank just fine.
