Topping off a large sand filter

[newbie2715]

I'd use some kind of funnel mechanism .. that way you don't get any sand in the middle pipe area ... just my 2 cents.

I used duct tape over the middle pipe... then cleaned it off. Fairly simple.

I am sure you know this but make sure the filter has water in it when you add the sand as to not put undue stresses on filter components.
