Duckweed in aqaurium?

Adamson

Do those of you who have planted aquariums have Duckweed?

I just got some today and put it in mine, and I think I got too much.. It is covering pretty much the entire water surface, and has made the "inner" part of the aquarium significantly less bright. I have heard that fish deaths can occur because it limits the amount of oxygen that can get into the water.. What are your takes on this?

I will post pictures soon..

I have trouble keeping Duckweed under control in my tank. I wish I'd never added it tbh as it grows faster than anything else. I am still netting it out 2 years after some first got introduced into the tank via some plants I didn't wash properly.

yeah I could see that.. I am worried about the fish getting enough oxygen now.. And will the lack of light kill my other plants?

I don't know what other plants you have, or the lighting your tank has, but if they're high light plants, then they won't like the shade for too long.

I am not sure what type of plants I have in there honestly, my lights are fluorescent with the blue tint that say they provide full spectrum daylight.. Here are some pictures to better understand my infestation.. All help is appreciated!





Thank you!

Nice tank

I'd scoop some of it out each week to keep it in check. That's the same issue I have where it's covering everything. Failing that you can have a filter outlet moving the surface of the water enough to keep the Duckweed at a certain end of the tank.

I have this over all my tanks, never had an issue with oxygen exchange, just make sure it doesn't get to thick, scooping out as much as you can every week should keep it under control, or something that keeps the surface water moving around such as a HOB filter will help keep it under control but will also stagnate the growth of other floating plants. Otherwise its a great nitrate sponge since it grows so fast.

Thanks everyone, yeah I have a canister filter so it moves it around a little bit but not too much, I will scoop some out after work tonight!

I have been giving my excess to a neighbor with Goldfish. They seem to be eating it.

By looking at my pictures can anyone tell if I have any plants that need a lot of light?
