Although it's November my pond (700 gal) weed is still growing and now
covers the surface. The fish snooze below. I've switched off the pump, but
I'm a bit concerned that not enough surface is clear to allow sufficient
oxygen to dissolve. Should I clear some of the weed? I'm not too worried
about freezing as I live on Vancouver Island, close to the sea, and it
doesn't get very cold . I hope I'm not tempting fate.

Thanks
