Haven't removed duck weed from my tank in about 4 months and now it looks like deep bayou sludge
​
My nice chihiro light does an excellent job of growing duckweed and hornwort that proceeds to cut off the light to all the nice, fancy plants that I spent good money on and killing them if I don't regularly pull the hornwort and duckweed. My emotional support dog died early May, but was facing health issues for a bit before that, so I just didn't have the mental energy to keep up with it for over 4 months now. However, a recent drunk visit to the Vancouver Aquarium gave me some inspiration for my tank and the motivation needed to start clearing out that duckweed.
I have threatened to break into a fish keeping friend's house and dump this in his tank, but I actually have a client who keeps koi so I give her what I pull. I dog sat for her a few weeks ago and there was not a single sign that there was ever any duckweed in that pond. But I've had to deal with this because of a single piece that slipped through when I bought plants online once 3 years ago 😭
ps the 3rd photo is an after photo it was worse 😔
