Cleaning sand of sand filter

[JAN]

Wonder if necessary to clean the sand of the sand filter?

See (mainly in US) there is a cleaner/degreaser product that one can use - yearly - to clean the sand that is inside the filter. 

Don't see such a product being available here in Thailand.

Question? Is it necessity and if so, what can one use and how? Thanks!

Most sand used in Thailand is of an inferior type than used in the west. (Generaly speaking)

Thai sand is stuffed at its best at 2 yrs unless silicate sand or Eco recycled plate glass.

Over backwashing is the culprit. Natives like to backwash every time they go into a pump room.

If you could wash it would only take out the broken down sand (Clay).

Best & more efficient is to change the media! See attached.

 

Beware the ???? on here saying that sand last for ever in rivers as this is a rediculous comparison!

 

Cheers

The sand cleaners as sold in the west are not really suitable for sand available here unless it is a sand high in silicate, then maybe it is worth a go, but with the cost of glass media here it is not worth it. Change it

Change to glass,I haven't looked back.

Your sand can serve you surely for years once you regularly backwash it. A quartz sand is laying in river and creeks for millions of years, always clean. 

(But I do not sell the river sand.)
