Floating Plants For The Surface

Hi
Can anyone recommend an easy floating plant for the waters surface ? I have Led lights on and a small 22 l tank.

If you want small floating plants for a small tank, there's always duckweed  This isn't as bad as some people make out, and you can always scoop out handfuls if it threatens to take over.
Or google Silvania natans and S. minima. They both stay quite small.

I currently have the water spite, Ceratopteris cornuta (not C. thalictroides) in my 180 litre which might be a bit on the large side for your tank.

Floating red root is great for a small tank. Bigger than Duckweed and much easier to get rid of if you decide you've had enough of it!

Hi
Might go with frogbit as I think all the others say don't like lids as it creates condensation !
That was on the aqua essentials plant guide . Unfortunately there also out of stock of it !ally

Hi Ally
An easy to grow floating plant to grow is Limobium Laevigatum. Another easy to grow floating plant and something a bit different is Hygroryza Aristata. It's from the water grass family. Looks are deceiving it looks like a stem plant, but it's actually a floating plant. 

These https://www.amazon.co.uk/Feeding-Square-Aquarium-Feeder-Floating/dp/B00UF0HTCM help "contain" floating plants, preventing them from getting buffeted around; the fish also seem to like resting underneath them given the full coverage they provide when filled with plants and they're not an eyesore at all due to the way they're disguised when sitting on the waterline with only the plant roots visible.

IME, salvinia natans is a much more robust, heavier plant which seems to sit better in one area on the tank surface and not be subject to as much buffeting as other floating plants such as Amazonian frogbit (limnobium laevigatum) or red root floater (phyllanthus fluitans).

I use this stuff, cut it to shape and support it with cable ties about 5mm below the water to keep the plants out of the skimmer. I have also penned plants in other areas to balance where the shade is for the fish. It allows free movement of the water surface so the skimmer still works. It is a good cow-catcher for filter inlets as well.
