My water lettuce was doing great for a year. They were growing like weeds and I was constantly needing to remove some because of overcrowding. Suddenly with no change in lighting, water movement or water parameters they started dying off. Roots were starting to diminish and melt away. I moved a few over to another take that had less light, more water movement but the same water parameters and those recovered and began to thrive. Put them back into the original tank and they died off. The reasons stated in this video are not necessarily the cause of die off. In fact in an aquarium setting these plants, especially the dwarf variety, prefer less intense light. Intense light can cause scorching in the leaves.

My water lettuce, dying 2, yeah, water lettuce only live on green water & it's direct on the sun light, I have fish pond, so my water lettuce on that fish pond are healthy, compared to water lettuce on my aquarium, if you want healthy water lettuce, just change your water into green water then find a place that it can see by sunlight,

Should we cut the brown leaves off?

I have dwarf water lettuce, I have lots of flow, maybe like 20 guppies n a piranha small baby. My lettuce thriving, I give a about 8-10 hrs of lighting. No added nutrients.. water change about 10% every other week..

I had water lettuce struggling in quite a few tanks. I set up a new one that had too high levels of phosphorous. The phosphorous was leading to cyanobacteria problems. The water lettuce exploded in that one. My theory is that this is an extremely phosphate hungry plant. Anyone agree?

All my water lettuce died, now I know why 👍

Mine was just getting too much sun in my pond I think

You don't have to add any nutrients to the water?

What is too many plants per tank? I have a 10 gallon and the majority of the surface is covered. Should I remove some?

I’m setting up a shrimp only tank that the moment. Would you recommend this plant?

Mine is kept in a small makeshift pond and having guppies in the balcony. I stay in Dubai, a relatively hot place. There is no surface agitation in my pond still they are turning yellow. What could be the reason?

U got me wanting to buy this plant:) amazon here i come!

water lettuce going yellow ,,,low nutrients under high light saturation or in high flow

This is super helpful, thank you. My water lettuce are tiny, are there different types or will they grow that big? Only had it a week.

But you need some water agetation at top to get oxygen in the tank don't you?

Water lettuce no need to filter they love atleast sunlight and the water is steady only u can put guppy fish and the poop of fish is the fertilizer of water lettuce then the guppy will eat the egg of mosquitoes

Thanks very very much for the nice & easy explanations ❤

They say surface agitation is important for gas exchanges so how do you keep floaters in when you also need to stir the surgace up for the fish to breathe

I got both water lettuce and frogbit and they are doing very bad! They keep turning yellow and roots rotted off! Idk what else to do. My tank does have a lot of flow so i tried putting a few in separate container with tank water and they still died. I use easy green once a week. I also have water whisteria in the tank and the leaves keep melting. Any advice? There are plenty of fish waste in water and I dose ferts

😭 I think I killed my water lettuce before it ever had a chance.

How do they do in unheated tanks?

I got some last night and they were standing tall above the surface and stiff but this morning it was flatter and not tall and straight up

Yellowing plants could need some potassium and iron

Do you cut the dying leaves off or leave them?

Thanks for the tips!

Will it produce oxygen inside aquarium
