Hi everyone, I purchased the Ammannia Gracilis a few weeks ago. After few weeks planted, the leaves of my Ammannia Gracilis turned black and crinkle. Could anyone identify the issue I am having with my Ammannia Gracilis? Thank you so much.

Looks almost like an algae issue

Hi marmaaa,
I am not sure if it is algae issue. But, it is like the stain on the leaves. Is there any way to get rid of it?

Black Beard Algae can look like that sometimes. It will be ingrained into the leaf sometimes. My Anubias was like that. What are your water params? Any ferts?

It could be a lot of things.

Ammannia's are tricky plants to grow, and few do it well. They prefer very rich soil and very lean water column ferts. Then again could also be issues with CO2, light, and tank maintenance.

There is a reason you don't see it much in "Dutch" type tanks. The same conditions it prefers can be poor conditions for other plants.

Wow- I just posted on another Ammania thread and ..fits perfect here too. I even mentioned seeing them in Dutch style tanks with heavy Co2 and light use looking large and healthy.
If in low tech? You are only renting them for a few weeks at most. You are better using that time for plants that like your conditions.

ammania is not an easy plant. ideally you'd have 0kh good co2 and lean dosing. this is a plant that has many issues with stunting, when growth parameters are not to it's liking. in a low tech tank it's probably not gonna survive. but it also looks like the old emmersed leaves are dying off and collecting algae in the picture. i'd snip off these and wait for new growth. cheers,
