    I just bought some pool filter sand at a pool supply store. It was $7.99 for 50# bag. It's mined by the US silica Co. and is called " Mystic White II premium pool filter sand." The bag also says it's "angular" sand, whatever that means. It has a 6.5 pH, so it's very slightly acidic. It seems like pretty good stuff.

    I've been trying to find sand for a reasonable price. I found the reptile sand but it was $9 for a tiny bag! [img]http://www.**********.com/iB_html312/non-cgi/emoticons/sad.gif[/img]

    I went to home depot and asked for Silver Sand and I got blank looks. Couldn't find it there.

    I went to another pet store and I bought a small bag of 'Estes' Ultra Reef' marine sand. It says 'Safe and non-toxic for a variety of uses: Marine aquariums - Terrariums - and other exotics' 'Safe for fresh or salt water'

    Any clue if this is CP friendly?

    Home Depots that stock useful CP sand are rather rare (based on my exhaustive survey of 5 stores in three states [img]http://www.**********.com/iB_html312/non-cgi/emoticons/wink.gif[/img] ). I have yet to visit a pool supply store (i did call one, but they said their sand wasn't 'coarse', whatever that means), but i think that's the surest bet of getting the right stuff. They're not likely to use carbonate-contaminated sand in a pool filter.

    You can do the acid test to check for carbonates (think vinegar and baking soda - it fizzes), but other than that all you can do is try it out...
    There's no 'a' in perlite.

    So is the sand Home Depot sells in 50# bags good for CP's or no? It just says general purpose sand..

    I would stay away from the Home Depot sand and stop by a pool store and buy some filter sand. The difference is like night and day.

    Just my two cents based on my experience with sand. General purpose sand bad, filter sand good. Your plants will thank you with strong healthy growth.
