I have a 55 gallon that’s been setup for a month now. I have some dwarf sag as a carpeting plant, but it is not growing very well. I would like to maybe have another carpeting plant that will form a more dense carpet. I like the look of Monte Carlo, but I’ve heard that it is very difficult to grow without co2. What plants would you recommend to use to make a carpet like Monte Carlo, just without co2?
