Alternanthera deficiency

One more question to this thread.
My echinodorus bleheri leaves are long but very narrow, I see that people usually has really wide leaves. Is this also because of lack of nutrients or?

Could you post a closer-up picture of those Swords - hard to tell from the pics you already posted. Mine usually gets very wide leaves as well. Perhaps yours are Echinodorus Xinguensis which tends to have slimmer/narrower leaves.

Cheers,
Michael

According to LFS it is bleheri

Hard to say 100% but looks like it. How long have you had them and how tall are they approx? I have everything from runners to super huge Bleheri - when the plant it young their leaves tend to be a bit slimmer.

What I do notice about your Swords however, is that the leaves looks too curly... that is quite likely a deficiency situation, so your added fertilizer dosing hopefully will remedy that situation.

Cheers,
Michael

The Left one has been planted 3 months ago. The middle and right one has been planted 2 month ago. The tallest one is around 50 sm.
 
So, as It was advised here I did following:
Reduced light intensity to 70% white 70% blue 75% red 55% green.
Light time (excluding sunrise and sunset) to 10 hours.
Daily 20 ml Special + Daily 10 ml premium(just to keep Iron level for red plants).
Today I have noticed green algae at some places.
Should I reduce from 20 ml to 15 ml?
 
Hi all,

I'd probably look on that as a good sign. Because the Green Algae belong to the <"same clade as all the higher plants">, they have the <"same photosystems and basic physiology"> so, in some ways, all it is telling you is that <"conditions are suitable for plant growth">.

When people have <"iron (Fe) deficiency">, and change their iron source, so that iron ions Fe++(+) become available, often the first sign is a <"sudden "flush" of green algae">.

The "advantage" iron deficiency has is that <"iron isn't mobile within the plant">, so it can't be shunted around to where it is required.

Algae don't have any vascular tissue and are <"reliant on nutrients diffusing through the cells walls">, meaning that they can start growing as soon as iron isn't Liebig's limiting nutrient. With vascular plants you get a lag phase before healthy new leaf tissue is produced.

What kind of deficiency do you suspect? Calcium?
 
Small update. I have removed unhealthy plants a week ago, got the healty ones from the small tank and planted them in the big one. So far seems really good.

I did some loooong reading on forum and seems I have lack of PO4, just did testing (yes I know they are not accurate), and it shows something like 0,2 ppm.
Should I start dossing additional PO4?

You may try. Dosing phosphorus is tricky because its efficiency depends on other stuff in the water.
Hey, @nijat11, I've read your water report. Or, like you said, water from your neighbourhood. There's a LOT of sodium in your water. Also alkalinity (bicarbonate content) is high. In sum, this is definitely not the water for a plant specialist. Only the hardest plants will survive in such a water. Neither is it good for your fishes.
My suggestion:
(a) If you want fishes which would revel in your water, go for East-African cichlids. You'll have to abandon all plants, probably. Perhaps you could try some strongly built Echinodorus. (Specialists on these fishes would tell you better.)
(b) Or get reverse osmosis, and use exclusively RO water. I know, you've got a very large tank. Still, it can be arranged if you're seriously in.

Yeah water seems very hard, but to be honest fishes feel really good. My angels spawn like crazy, corydoras spawning very often, ancistruses spawning non stop.
Crypts doing amazing, echinodoruses also not bad, but some problems need to be fixed. As you can see from the last photo alternathera also stars to grow, for now I have problems with buchies, the lost a lot of leaves, but now starting to grow back, and rothala h'ra also growing not good. I will try to find report for my village as well.
 
So it seems that you can still keep some plants, and if it's ok with you, then perhaps you'll have to tune up your ferts a bit ... and enjoy your fine looking tank. 🙂
