I have water hyacinth aquatic plants for sale for your KOI goldfish pond. The plants are healthy and they will turn your pea soup water into clear. Water hyacinths have been used for water treatment for human consumption. Imagine what it could do for your fish! The plants are also sold at local garden stores (Wally Aquarium and MerriField Garden Center). Mine looks much better. They will multiply in no time. My KOI fishes grow fast because I overfeed them (I shouldn't though) because I know the water hyacinth will purify the water for me. Water hyacinths are the cheapest and most effective investment you can do for your KOI / goldfish pond. The price is firm. $4 per each plant. buy 5 get 10 FREE ($1.33 each) buy 10 get 30 FREE ($1.00 each) buy 15 get 55 FREE ($0.85 each) Email or call 703-983-5887 if interested.
