i have a rio 125 and will have 2.2wpg and co2 injection and i would really like a carpet plant so what do you recommend. i'm thinking dwarf hairgrass at the moment
HC or glosso, both would probably carpet in your tank, think its the same one that George has and he got great glosso carpets at jsut over 2PWG. Both benefit from a nutrient rich substrate and will look stunning if done right.
