    Hi all,

    I'm new here, (and new to aquatic gardens), I want to start IE dosing my tank, but I haven't found where to buy KH2PO4 in small batches where I live (Costa Rica), only wholesale 25kg bags.

    So, I was wondering if I can use orthophosphoric acid (H3PO4) as a source of PO4, because it is more readily available here.

    Cheers,
    Juan

    5 mls of Fleet Enema (look in pharmacy) has the same amount of PO4 as 1 gram of KH2PO4.

    Dosing calculations for Fleet Enema are also included in ACP's Fertilator, and in my StockSol Spreadsheet.

    $7 133 ml bottle of Fleet Enema on my nearest pharmacy, the equivalent of 26.6 grams of KH2PO4.

    Thanks a lot to all!
