    I thought this might be a solution to one of my many pond problems but it raises more questions than it answers.

    I've checked out the website (thanks you firefly0) and the principle of the process seems to be the disruption of photosynthesis in submerged plants. What about the submerged oxygenators? presumably they will be affected equally.

    Like insecticides and weedkillers it seems to me to be rather unselective and therefore I would proceed with caution if at all.

    If you get the right amount of plants in the pond the water will be perfectly clear no need to buy stuff.

    I agree Lyn ... our small pond has a bit of duckweed and the occasional bit of blanket weed in the spring, which we occasionally remove by hand, but most of the time the water is kept beautifully clear by the oxygenating plants and lots of pond snails who munch on the algae, blanketweed and duckweed.

    Before the colony of pond snails had established itself we used Blagdon's Barley Straw Extract occasionally to deal with blanket weed ... it was very successful and perfectly natural and didn't harm the frogs, toads, newts, grass snakes and many invertebrates who use our pond.

    When I moved here I was astonished at the number of pond snails I had. I haven't seen any recently and now I have blanketweed. image

    We started our pond snail colony by buying some online (from a reputable supplier as I didn't want to introduce any problems to the pond)  ... however I wouldn't do that until I'd discovered why your existing colony seems to have disappeared.

    I have absolutely no idea.why Dove. There were squillions but I haven't treated the pond with anything and there are still loads of froglets and fresh water shrimp. It's jiving but just not with snails.

    I guess the interest rose because Gardeners' World recommended the dye on Friday's show.
