Sand in the filter got hard - how to take it out?

Postby Hankiss » Sun 17 Jul, 2011 14:58

Hi everybody, I need some help. I have recently changed sand in my pool filter. But after two months it got hard like a concrete. Therefore I have no circulation. I need to take it out and change it again. Is there any chemical which can make it soft again (in order to take it out). At present it is solid hard and I cannot take it out. Why it got hard so quickly? Thank you for your help. :(

I have the same problem, if you should find an answer please post the answer. I thought it was my filter, so I went and spent 600 dollars and bought a new one. Today when we closed up the pool, the same thing happened. Hard sand, hard as a rock.!!!
