Agreed I don't think it was a .22 um.

Something you can do is a double filter process use a .45 then use a .2. So filter using a .45 then dump in a .2
This works fantastic with deca.
It cleans it up really nicely and the biggest thing is it takes less pressure off the pump than using .2 and spending 3 times the time. Check it out.
