Have a Jacuzzi pool sand filter MFM17.
The owner manual saids it takes 150 lbs. of sand. But this seems to be wrong I think.
There is a grated basket in the filter about 10” below the top called a deflector basket. If I put 150 lbs of sand in it will cover this basket.
I thought the sand should be about 1” below.
Is it better to much or to little sand

Any suggestions
thanks
