    Hi,

    Please confirm my calculation, does 150 mg of Na2HPO4 give about 1.25 PPM of PO4 in 80 liters of water?

    Well, recently it seems the only place in Thailand I know that sells KH2PO4 in small amount
    has closed down. The other convenient choice is it.

    Thanks

    PS: Please don't suggest switching to Fleet Enema.... :)

    =94.973/141.96*150/80
    =1.254398245984784

    Yup, you're good.

    Definitely no sense buying fleet enema if you've got pure Na2HPO4. Heck you could even sell your own home-made enema kits to other people :D

    You might be able to use a goose with a gush to help with your Na2HPO4 kits. LOL

    Not a thing if you don't count expense; the cost is 3-4x as much for the same quantity of PO4 shipped to your door in the form of KH2PO4. This is assuming you only order 1lb for $2-4 plus the $6 flat rate shipping, which usually allows for up to 3lbs if I'm not mistaken.

    If you can get things from SG, then Dr Mallick's is good for most items.

    Order some and get a lot in.

    Then you will not run out for years:)

    Thanks, Dan. :)


    I'm afraid I can't. Unless they (Dr Mallick's) would label it as something else.
    Importing chemicals that falls into fertilizer category is still troublesome.

    Actually the info is for telling people here where to buy PO4 if they're interested in EI.
    My 1 kg bag of KH2PO4 still doesn't look depleted a bit. :)

    My Goose Gushed

    Hi Nipat, All,

    Never would I recommend Fleet Enemas, well okay I might. :p

    The Wal-Mart knock-offs run under US$2.00 for 236-ml, that is a year’s supply for an 80-gallon tank, all mixed, easy to measure and so far no government restrictions on them. :)

    At least no restrictions until the teens and college kids figure out some "off label" use for the stuff... :)

    They can't restrict Fleet:)

    The stuff really works. I haven't seen GSA in a few weeks now.

    I can see the news story now. "He snorted what?!"
