A fellow fish-keeper suggested I try Cloverleaf to stop the blanket weed.
It does not contain chemicals and will not harm plants/fish or your filters - and most importantly, it works. I think it comprises diatoms which coat the blanket weed and starve it of light and nutrients.
The water looks milky for about 1 day then clears. The blanket weed will be mostly gone in about 10 days.
If you have a lot of it, then best to pull out the dead b/weed to stop it decomposing in the bottom of the pond.
I find 1 dose in March usually lasts the season, but occasionally (like this year) I've had to re-dose. And if you dose early before the b/weed gets a grip, then it doesn't appear in the first place.
Would also agree re. the watercress. I grow it in the header pool and it cascades down the waterfall - and yes I do eat it :)
