Sunspot, am doing my homework prior to starting a slow sand filter.
You are right not to back flush, it destroys the filter.
The finest sand goes on top just like you are doing.
Did you pre-wash the sand?
What did you do to make sure you had no air pockets in the sand?
Have you got it working and how is it performing?.
