Question about pool filter sand

[Orgeno]

hi everyone, I’m planning on replacing the sand on my filter, I have 20” Jacuzzi Mfm20 sand filter and on the tank label it says “silica sand 48 effective size” and it takes 250lb. Just need to which sand grade I need to buy. Thank you in advance.

1st question is why are you replacing the sand?
Sand doesn't wear out in the filter, that is pool industry lies, it can get very dirty though so worth cleaning.
If you are replacing then use the best Dr Drydens activate AFM ng, the best makes looking after a pool easier

Thanks for the reply, the filter is working fine as of last season been using the pool for 3 years now I read it was recommended. So don’t fix what’s not broken.

Sadly not true, the sands been around a few million years so 3 years in your filter wont harm it BUT, giving a good clean is a good idea. Just dont let any cleaner get into the pool so valve it off or block ports off but a good clean works wonders. As I said earlier changing to AFM makes a huge difference and the ng version will be amazing. I have been running AFM for about 17 years its been really good but swapping to the ng version this year.
