the substrate is really no concern for red plants, they don't require any different nutrients that green plants, all they need is super intense light.

3 bulbs at 54 watts each? should be good.....how far from the substrate will your light be?

Most likely 21-22ins , sand will be 2-3ins deep

yeah you will be okay.

watch the new growth, if it comes in greener than the old growth lower your light height if possible.

there is a misnomer out there the lots of Iron will make plants red, but thats not true, i can attest to it. high light is the best way to get good reds. that and a healthy aquarium. i would still give root tabs, or another form of ferts to help your plants stay healthy, but as long as you give good light, and keep up with water changes your plants will grow well.
