How much sand in filter

[CarlD]

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

Call the company and ask--that's easiest. Are you sure that basket is supposed to stay in? On my filter, it's a shipping and winterization tool that stabilizes the vertical pipe. Ask for technical support and have the model and serial number of the filter ready. I did that with Hayward since my filter and pump aren't a matched pair and they were able to reassure me they work fine together--6 years later they are still fine.
