blue powder for ponds

 Nick Bailey added some blue powder to his wildlife pond ( in the may 20201 programme ) to help with algae. What was the name of it and where can I get it ?

    @lydiabrindley1I51giT-o -It happens when the water warms up. It won't harm wildlife in any way. Once the temps cool down, it'll fade. It can also take a few years for a pond to be balanced, so if it's a new pond, that can be the reason. 
    If the pond's in a sunny site, you need some plants which will give cover to the surface. Ideally, around two thirds needs to have cover. Oxygenators will also help to keep the water healthy. 
    Have you got any plants in there? Some photos of your pond will help with advice  :)
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...

    @lydiabrindley1I51giT-o, try Nishikoi Clear Waters. It works brilliantly in my pond, much more so than barley straw. I have scores of newts in the pond.
