Mysis Shrimp Stink!

[MarkoD]

so i've started feeding PE mysis shrimp to my tank and i've noticed that it leaves a film on the surface of the water and stinks everything up.....

i cant even get the smell off my hands (washed over 10 times with soap)

I have 2 powerheads pointed at the surface of the water but it doesnt seem to be helping with the nasty smell

any suggestions?
