Hi. Ive tried several chemical solutions to get rid of duckweed with no success. Koi goldfish dont seem to mind it but it continues to spread across surface. Any ideas how best to get rid?

you need more fish! Yay, I get to use one of @addy1 's acronyms (MFS) for the good! I say this because I can't KEEP duckweed in my pond--the fish just suction it down! Seriously, I have to grow it separately and it's now a fish 'treat'. So, yeah, I'm giving you license to now get more fish; you can tell any significant other that! :cool:

Mg fish are still to surface this year. Are you saying when they do that they will eat the duckweed. I havent noticed that in previous years

tell you what; stop feeding the fish and see what happens! But yeah, if you actually have an abundance of duckweed, try feeding every other day and less until the duckweed is all gone.

I've noticed via my underwater cam that at 50 deg F is when the fish really start moving around. Check your water temps.

Also, are you sure it’s duckweed? I’m one of those people who can’t keep it, because my goldfish gobble it down immediately!

I wish I could keep duckweed. My fish devour it!
I keep it in a floating net. When the nets fills up, I'll release some for them to eat. If I didn't keep it in the net, it would gone in the blink of an eye.

Mine gobble it up too fast! I have to keep it in a small separate pond and dole it out to them now and then!

Does anyone collect duckweed from wild ponds or lakes? What are the risks and can they be mitigated. Note I only have (rescue ;) ) feeder comet goldfish.

I do, then grow it in a bucket, to allow any pests time to settle out. You can also try floating your wild gathered stock in a bucket of “dip” a dilute bleach or potassium pomegranate ( that won’t be spelt right on the pomegranate) then moving it to fresh clear water for a thorough rinse, before setting it up in a separate container to grow and doling any out.
