I have an inground pool, 40 cubic metres, with sand filtration system and I use chlorine tablets.

 

The time has come to replace the sand in the filter and I have been reading about filtration balls which seem to have only come to market in the past few years. From the reviews I have read they seem to be far better than sand but I was wondering if anyone here had switched to them and what their experience was.

 

In particular, how they interact with flocculants or clarifiers. I did read on one of the sites that sell them they they are not compatible with such products which seems a little strange to me. So again, any experience would be of use.

 

I have read the previous thread but that was 3 years ago so I thougt it was worth starting again to se eif anyone had more recent experience with them.

 

Thank you.
