Hi

My dwarf lettuce is making a mess of the tank. I was doing potassium and seachem flourish but since returning to work haven't been able to keep such a regiment dosing regime. It was looking great beforehand but I stopped dosing potassium and only use the flourish now. The main issue I'm finding is lots of tiny leaves..they're making an absolute mess. Can anyone advise?

That's my thought too. I managed to get duckweed in my tank from somewhere and it made my frogbit look like that :mad:
 
I concur with others, the tiny plants are Duckweed. Water Lettuce reproduces by sending out a quite delicate whitish runner from which another plant will grow at the end.

And just so you know, there is no separate plant known as Dwarf Water Lettuce. The sole species is Pistia stratiotes, and it will grow to whatever size from an inch across to a foot, depending upon conditions (light and nutrients) in the tank (or pond).
 
FYI. I have one tank that I take a few minutes each day to pick out the duck weed I stupidly put in the tank. I thought I had it all but now it is almost back up to the original numbers.

Just so you know. ;)

Just one of many such references.

You will note that the author of that article has only one scientific name, as I said earlier. And that is all that matters, the scientific name of a species; s different plant species would have a different accepted name. If the plant grows variably depending upon tank conditions, it is still the same plant. And I have had plants less than 2-inches across in some tanks, and the same plants when put in my outdoor pond during the summer grew to over 12 inches across. They are the same plant.

This is just another example of citing "references" written by individuals who do not understand or know. Read the botanists who do know, Kasselmann, Hiscock, the International Plant Name Index, Kew Gardens database are some.

I know all about scientific names and 'common' names, but again, you have failed to appreciate that when many members use what they believe to be accurate names, they use what they find on respected sites as their references. I've also studied more than those botanists and references you refer to.
Regardless, to say that there is no such thing as 'Dwarf Water lettuce', when you can read about it on respected, established sites and actually buy it, is just wrong.

There is no such plant species as Dwarf Water Lettuce.
