    The quantity I needed at a great price, and fast shipping!

    Like the title says, I was able to order 25lbs of aluminum sulfate needed for my plants, at a price that could not be beat, even with shipping. My order got to me in 2 days. Very happy with my transaction.

    Wish it came with instructions...

    I need to lower the ph in my soil. I purchased aluminum sulfate because it works more quickly than ammonium sulfate. I was hoping there would be some information about rate of spreading (e.g. lbs/1000). Something like pools use for adding chemicals (eg. if you want to drop it x use y rate).
