    Q
    How much Crystal Plex do I put in a 300 gallon pond with fish?
    A

    According to the manufacturer for a 300 gallon pond with fish (not trout or koi) you will use a total of ¼ oz (1.5 tsp) of Crystal Plex Algae Control.  When there are fish in a pond you want to only treat ½ of the pond at a time, so 1/8 oz( ¾ of a tsp) in half and then 5 days later you should treat the other half with the other 1/8 oz (¾ of a tsp) of product.
