Which brand did you use and how are the plants growing
I'm using the catalina setup and the plants are growing fine. That said, I'm hardly challenging myself: bacopa austrailis, sagittaria subulata, anubias barteri var. barteri and vals.
With co2 the bacopa need trimming every two weeks. Generally, things grow at a stately pace for me, but ymmv. Definitely problem free with easy growers in my 54 gallon.
Feel free to let me know if you have any other questions.
