Use in existing ponds! Also great for new ponds and springtime start-up!
If you want something EVEN MORE concentrated, consider Practical Garden Pond's choice of "Super strength Beneficial Bacteria" which is made for extreme problem ponds. Although it is an even stronger concentration, the dosage on Super Strength is also stronger because we expect it to be used in extreme situations where just a double dose is not enough. First aid for the dirty pond!
