Cardamine lyrata

[Joy]

Hi fellows,

I planted Cardamine lyrata in my new tank along with other plants, the details are below
Size: 140L/37G
Substrate: ADA Amazonia New + ADA substrate additives
Fert: ADA Green Brighty Step1 and Brighty K
Light: 0.6 watt per litre/ >2 watt per Gallon
and CO2

For first two weeks the growth of Cardamine lyrata was very impressive, in fact in the third week I did a little trimming also. But suddenly it started turning yellowish, specially new leaves and the new leaves are smaller in size also. So now I am very depressed to see this.

Can any one please let me know, what is the problem, and how can I fix it?
And also, how important the Lily pipe is, for planted aquarium?

Eagerly waiting for your responses.

Joy

I can't answer all of your questions, but I had a similar experience with cardamine. I bought it on a whim, and the leaves started yellowing and the new growth was smaller. I read someplace that the plant is not ideally suited to tropical tanks - I can't remember now, but maybe it was temperature(too high) that was the issue. Amazingly, I still have some stems of it, but it has very small leaves. My tank was gravel at the time I got this, with excel dosing and flourish, with high light.

If you like the look of the cardamine, it might suit you to get some pennywort. It really does look the same, and grows really well in my tropical tanks.

Also, I have no idea what a lily pipe is, so sorry to not be able to help.

Is that the only plant species showing signs of shortage? sounds to me like you need a bit more iron.

A lily pipe? Not sure what you mean. I prefer a spraybar myself because my tank has fish as well as plants
