If you are in TX, the water from the tap is hard more than likely unless you are using RO. This plant will not fair well. SAE's will eat it, it's just food for fish and somewhere for algae to grow.
Red plants: try a red color bulb: GE 9235K etc, Giesemann aqua flora etc, Gro lux etc.
Buy plants that are normally red and then focus on general plant health.
In general, red signals a stressed plant or undeveloped tip growth where Chl a has not yet been incorporated. Many on line use photoshop to redden up the pictures. Trust only what you see with your own eyes.
You can redden plants up temporarily, but it's not a good longer term strategy. Lower light is as it can allow lower rates of growth, thereby lower nutrients that stress the plants without it being such a slippy slope, but many who believe lower ppm's are the key, do not want to use less light.
So they put themselves between a rock and hard palce.
I do not worry about it and focus on growing plants in generla and seem to have nicer colors. Might be something more to that.
