  • Best Bio Media for Sand filter Conversion?

    I'm reworking the backwash piping of an old Hayward sand filter I acquired last year, and I'm wondering if any of you have thoughts as to the best type of media to use.?
    I'll need about 2 cu.ft. for the filter.

    pool filter sand. can be found at any pool supplies shop, a fav of boxers is leslies pool supply.

    basically it would be like a large fluidized bed filter and those things are awesome biological filters.

        Not really... a pool filter's sand media is designed to remain at rest and to be a mechanical filter. It must be backwashed daily to flush the debris from the sand. In a fluidized bed filter the individual grains are suspended in the water column and is strictly a biological filter.

        What are the facts? Again and again and again--what are the facts? Shun wishful thinking, ignore devine revelation, forget what "the stars foretell", avoid opinion, care not what the neighbors think, never mind the unguessable "verdict of history"--what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your only clue.

          It depends on the type of filtration you're after. PFS will work fine as a mechanical media, but must be backwashed daily to flush the debris out of the sand. If it doesn't get backwashed it quickly becomes clogged.

          If you want a biological filter then the water tech media will work.
