Eustralis stellata, not coloring!

I have had eustralis stellata for the past 3 weeks or so and the plant has not yet gain any color but all green.

I have 3.25wpg 6,700k and dosing plantex csm + b plus extra iron from GW. Would someone please tell me a way to get my eustralis stellata colored up?

never grew that plant, but sometimes red plants get redder when nitrate is low.

HTH...This is from one of the online vendors: I think it is from Tropica:

Eusteralis stellata is a brilliant indicator for micronutrient,especially iron. If the aquarium is short of iron, the leaves will turn light green to yellowish but a few days after iron addition the colour will reappear on new leaves. Occasionally, the plant suddenly stops growing but after a while adventitious shoots will normally develop and the plant resumes growth.

Mine is still pretty yellow and I dose a little extra Seachem chelated iron and it colors up a bit. But mine is too far from the light still to get the bright red orange. My first attempt at it so a learning experience for me as well. And my Nitrates are too high, because I keep too many fish in this tank and feed them alot so that might be part of the problem as well.

Mine are about 4" from the top of the tank, maybe I should try the seachem iron bottle?

Add more iron and PO4, reduce NO3

Careful not to stunt it with low NO3.
It will get very reddish at low NO3, but it'll also stunt easily.

That is why it stops growing.
The reason is very clear if you know what to look for(like myself).

It also appears to need some more Mg also than some other plants.

And what in general are you looking for Tom? Do you have time to elaborate?Perhaps you can even put a number on it for us based on your experience. I'd be curious. Like under 10 ppm of nitrate, but not less then 5ppm? At what point (assuming all other things optimum) does stunting generally start.

I imagine a root tab helps too. I put a few under one side and the plants grew faster on that side, until I added another on the other side of a row. Now the second side is catching up. I see a tiny bit more red when my NO3 dropped to 10 and added a bit of iron. 10ppm NO3 is fairly low in my tank.

Less than 5ppm NO3.

Plants get squirrlely under 2-5ppm and generally stunt.

N stunts growth more than other nutrients.
P is very hard to stunt a plant with on the other hand.........
It may slow growth, reduce O2 production etc.

Honestly, while you can do and maintain low NO3, it is something you need to be really good about otherwise you will louse the tank up, most folks do.

If you decide this is something you must do against this advice, well, try less light, slow things down, so that it is much easier to maintain and dose 2-5ppm ranges of NO3.

Tom Barr
