Has anyone used the silver discs that are commercially available to keep their water butts clear? I’ve seen them advertised but how good are they?
I’ve also heard about a seaweed product.
Would love to know what other gardeners do - as although I’m aware we should keep using the water to cycle it and scrub our butts out yearly, I’ve previously done nothing more. I’m now aware with temperatures rising the issue of preventing legionaries disease is even more important.
I’d welcome thoughts.
Thank you.
