Unbeatable price in my opinion and possibly a price mistake?
Amazon charge virtually as much for a 25lb bag.
Buy now before it's too late!

I've had a pool for 5 years and have never heard of using this stuff. our pool often gets 90% ratings when I water test it. So I'm not sure I even need this.

It's for DE filters, but can be added, in small amounts, to sand filters for increased filtration.

Good deal, but literally just bought 24lbs at Lowe's yesterday for $36 with Military discount. Which will last me a few years.

What does 90% ratings mean?

i hope you don't have a DE filter, b/c that would be weird if you did

Damn. Been a while since we bought a box (we usually get ours as Lowe's) and I had no idea the price had increased so much.

Food grade DE is recommended for those purposes.

There is nothing special about this price. If you buy this at the end of the summer, you can get it as low as $20-$25.

I bought this last week for $60. I tried to get Walmart to refund the different but they refused. Walmart offer $15 promotion code and tell me to return then reorder.

Is this different from typical diatomaceous earth? Not sure if it's a mixture, don't see additives list anywhere. If it was general purpose I'd expect the specs/listing to at least mention other uses besides pool filters.
