    Silica Sand=Filter Sand????

    I ordered a new Sand Filter....I checked locally and was quoted $700 plus sand at the local pool store for a 24" filter. I got one on ebay, shipped to my door for $220 (inc. shipping!!!) It's a 25" 300 lb filter.
    Now I need to find a good deal for the sand....lol...The cheapest thing on a pool is the owner!
    The local pool supply wants around 16 bucks for a 50 pound bag. I called home Depot...they said they didn't carry it. I called a local building supply place and they said they had silica sand in two sizes....20/30 and 70....I asked him if that was the size of the grain or the number...he didnt know. In any case he's selling his stuff for $14.25 for a 100 lb bag.
    My question to you experienced guys.....Should I go with the actual "filter sand" from the pool supply or could I get away with the building supply silica and if so ....20/30 or 70??? Or is this not enough info?
    Thank

    If you check Ace hardware or True Value, they will usually stock some. I recall paying somewhere around $7-8/bag

    You want grains from .45 to .55 mm, which is also known as pool-grade #20 silica sand.

    That's what I understand...I wonder if that's what he means by 20/30????

    likely referring to US Standard Sieve Size. the 20/30 sand particles are likely smaller than the #20 screen (.85 mm) but bigger than the #30 screen (.60 mm)
