Ive got a 2213 on my 11.4 and the flow is a dribble. I can't imagine the 2211... other than that have you seen the little yeast DIY setup on Amazon for like $13?? Has a little flow valve and links up two 2 liter bottles. Couple that with a little Griggs reactor that you can DIY on the 2213 and you'll be in great shape. You'll just need to mix up a new yeast sugar batch every 2 weeks.
Rotala Macandra is very difficult. Even with perfect CO2 I hear many have problems with it. Ludwigia Ovalis gives some decent red and it's pretty hardy. Or if you're looking just for a stem that will grow nicely and densely Bacopa Caroliniana is a good one
