What's your photoperiod? I run my lights for 8 hours, and my Ludwigia's red as heck. Too long, and algae takes over.

I've got Ludwigia in my shrimp tank. It's not super red, but the shrimp love it. Maybe they're keeping the nitrates low?

Thanks for the tips, everyone. Gonna tweak my ferts and see if I can get those reds to pop.
