Ammannia Pedicatella 'Golden'

[Hufsa]

This might be a silly question, but has any-one grown Ammania (Nesaea) pedicatella emersed?

Then you could play with nutrient ratios without having to take CO2 into account. I'm guessing that it will be a lot happier emersed <"and may flower">, which would help with naming as well.

I have some growing emersed, but i almost killed it off with the low and angry Norwegian sun this summer. Its recovering but not as big yet as it was.
It may come as a surprise to forum goers no doubt, but i am in fact even worse at keeping terrestrial plants than i am at keeping aquatic ones
It doesn't seem fussy emersed, growing fine in some tropica soil. Not sure i have the motivation to play with the nutrients though

A quick update on the Ammannia Pedicatella.
It appears to be growing ok at APT Complete levels of dosing, moderately soft water (GH6, TDS about 120), CO2 - about 1.2pH drop
The main change is to flow - I replaced the Lily pipe with a plain villa straight outlet pipe - so I guess the water jet is more focused, hits the opposite side of the tank harder and more water is pushed down to the substrate level.

Any plans to further unstunt it?

i'm not sure how... any advice? - though I suspect that some of the stunting in the photo is caused by overcrowding and certain stems getting shaded.....

if lean dosing per se is not the 'solution' for unstunting, I don't have many options left. I don't plan to try RO/DI water because I prefer the convenience of using regular tapwater....

It looks beautiful!! That colour and shade of yellow is so missed in the hobby. Red is old news...NEED MORE YELLOW!

Light is good..
Co2 is good
Maintenance is good…
That leaves ferts.

What is your current dosing? Please include Npk Ca:Mg:co3 (if possible) and all micros, ( I think you tried seachem?)

I am using off the shelf ferts so I can't vary them much. Weekly NPK will be:
NO3: 5.8ppm
PO4: 1.7ppm
K: 5.7 ppm

According to the water report my water GH is around 6, KH around 3-4. TDS meter of tap water is around 75-80ppm. My tank water TDS hovers around 110-120ppm.

Based on some comments that I may need to add traces, I am adding 5ml Seachem Trace and 5ml Seachem Iron weekly after water change (Yes expensive diluted water, but 5ml/week I'll manage...)

All from no3? Or nh4 as well.

sounds good. My remineralised tds is about 80ppm.

Based on some comments that I may need to add traces, I am adding 5ml Seachem Trace and 5ml Seachem Iron weekly after water change (Yes expensive diluted water, but 5ml/week I'll manage...)

how much Fe weekly?
The ludwigia senegalensis seems to have improved a lot. I think seachem trace played a role.

Hi all! I have tried to grow this plant in hard water in two different tanks, with co2 and good light, but it melted within 3-4 days.
Tried from different suppliers, still no success. Will it grow in hard water or just give up?

 

[_Maq_]

I've never attempted keeping it in hard water. In my soft-water tanks, it doesn't melt but stubbornly features nutrient imbalances.
From that I derive that soft water is preferable.

Here's a more recent image... I have switched to a lean(er) Tropica Specialised dosing regime.

I too grow it in relatively soft water - as mentioned above, TDS meter reads 100-120ppm. It probably isn't impossible to grow it in moderately hard water but I wouldn't be able to advise you how to do so

Well it is not moderately hard, it is very hard 350-400 ppm TDS.

Well it is not moderately hard, it is very hard 350-400 ppm TDS.

That would make it very challenging. What you can do is to try with an "easier" softwater-preferring plant like Rotala Macandra. If it thrives, I think you got half a chance with A. Pedicatella.

If you are prepared to 'invest' in RO water and maybe dilute your tank water to 200ppm+, I think its possible

Well for me RO is a bit hard. I have 800 liter tank + 250 liter sump. My wife will be very unhappy if I will get a additional container for RO

+ 250 liter sump

What for? Do you think that a smaller filter would not suffice?

Well, when I was ordering aquairum, decided to go with a big sump. More place for media and equipment.

For reference - Ammannia Golden in open-air concrete tank in 30 degree+ Singapore heat. I suspect undergoing conversion from emersed to submersed. Their emersed form looks a whole look bigger than the emersed ones that Dennerle sells.
