How do I change my filter sand?

Make sure that you purchase enough sand for your filter, depending on whether it requires 2 or 3 bags. Turn the pump off when replacing the sand and open your filter, removing all the sand carefully ㅡ you could use a plastic cup to do so. Try to avoid damaging any underdrain fingers during the process. Add the fresh sand to your filter until it is ¾ full. Backwash and rinse for 2 to 3 minutes, to remove any residual dust. Finally, set your multiport valve to ‘filter’ and start your pump again as usual.
