I received a Echinodorus"Rubin" recently, and after one week ,leaves began to yellow despite Eco -Complete and Flourish Comprehensive. I removed the yellow leaves that did not seem to get better after another week, and the new growth from the center of the plant at approx four weeks, is indeed red to slightly dark brown. With low light,I don't expect the red leaves to remain red but they are quite pleasing to look at when they first appear.
I was also making the mistake of dosing flourish directly after a water change and have since corrected this Boo Boo.
Lee, if the plant receives direct light it will remain reasonably "red." I have a few of the red cultivars, and they remain sort of reddish-brown depending upon the cultivar but only if they are under the light with no intervening plants. A good location close to the front (remembering their larger size) as opposed to a back corner for instance.

Brad, on your initial comment of Flourish every few days I want to ensure I was clear; Flourish should only be used once or twice a week, and at the stated dosage on the label. It is quite concentrated.

Byron.

Thanks, Byron,
The Sword is approx five inches from the back glass in one corner, with Leopard Valls behind it. I could move it closer to the front, but am fearful of pulling it up at the moment for the approx ten new leafs beginning are quite young . But I have noticed that there is more light hitting the front of the tank despite me moving the fixture as far back as possible.
To be honest ,when I first received the plants from a source often mentioned here,they were crammed into a box that one might be able to fit a phone book into with one small cool pack that I would guess thawed in a matter of a couple hours. It was very warm, and with the exception of the rubin sword and anubia's,, the plant's were in poor shape.(some 40 plants)
I would not do buisness with them again and it is for this reason also,, that I am hesitant to move any plants at this time.
I will take on board your suggestion and if the newly forming leaves begin to look poorly,, I shall move the plant.

Agree. Swords do not react negatively to being moved as long as it is not constant. After 3-4 weeks, move it forward if you want it closer. Some authorities suggest trimming sword roots regularly to maintain better growth, though I've never done this. But it is part of the fact that they can be disturbed though not excessively, and will not react as crypts would.

Yeah only adding a couple times a week so far (flourish), might have cheated some in when I noticed the yellowing but not terribly bad. On the eco, I only added two bags and then put reg black aquarium rock on top of that, its possible that the roots are not even seeing the eco complete due to it being deeper. My substrate is up to 4 inches thick in places.
