Hey I recently purchased my family's first above the ground pool. 20'x52" round from Intex. After last summer's realization to the fact the the filter that comes with this 10,000gal monster is a cruel joke. So this year I am buying a sand filter and a vacuum. Well everyone says something different: #20 pool grade silica sand- no regular sand works the same, then you got 50lbs for $30 or $10 but it only says pool filter sand. So then I read about filter glass and ZeoSand. Anyone have feedback? Thanks
