Whats the secret to keeping Red plants Red ?

Could Ians good red growth be the combination of luxury availability of nutriernts and CO2. Double EI dosing and good flow, I have had red stems grow through a surface of Duckweed which obviously considerably reducing light.Depends on the plant I suppose
 
This morning....the dump continues.... Guess what I might be clearing up at the weekend, if the rain stops long enough.....

It would seem that even the specialised scientist don’t really know why but the presenters were swayed toward the red colour that appears in autumn leaves is a way to protect the tree from strong sunlight as the rest of the tree is shutting down for winter.
 
my thought.... our aquatic plant is similar like terrestrial plants... they also need fertilizer for growing and flowering...

while you have a dense stem plants that's actually not red at all... then you must try to lower your nitrate and keep the others higher... (i mean not put any nitrate at all... but less amount as before)...

but... this is not enough for absolutely red...

did you ever read Tom Barr said about 'such dark tanks with supposed hight light'....

or... our elder told us to put out the plants in the morning or evening?

i learnt and i found good article from here...
https://barrreport.com/articles/light-in-planted-tanks.48/

so... uv can build the anthocyanin...
blue light (indigo) about 390-400nm, actinic (420-430nm) can make your rotala too bloody... (i tried and the article is proven) and a less uv-a light about 360-370nm...

if you tried some led bml with this blue light specification... and you will know the truth of "high light"... 😉

the light is warmer for my eyes... and more dark as high light... but... actually the plants not respond with eyes for build the anthocyanin...

sorry about my English...

I have consistently high Nitrate, usually 35-40ppm and my red plants seem good and red to me.

Perhaps it's a matter of perception. The red I'm happy with may look too washed out for others.

I often wonder when reading that people are not getting reds, is it just that you are looking for an unattainable level of red?

I'd be interested to see photos of the red plants that are not considered red enough.

Would all depend what species you have though? Stuff like ludwigia sp red and alternanthera will stay red with high nitrate. However plants like rotala h’ra, ludwigia arcuata and hygrophila pinatifida need to be starved of nitrogen to bring out the bright reds you see in pictures.

i mean about rotala and the other red plants hide behind the green...

if you try your dose for rotala... the best color for them maybe orange or magenta form... (in uv light)...

but if you desire bloody red color of them... the optimum growth is the best for lowering nitrate...

i like to see the truth of rotala anyway... any species of them is interesting plants in uv grow light... you can see the truth of them and every variant has a special color...

i just see the pink martini color on rotala ceylon (sp pink)... they become whitish pink leaves with the shoot leaves grow like marcandra form... incredible...
