1) 15 inches
2) Dose flourish 2 times a week
3) 10am-8pm daily
4) 10am-8pm
5) pH-7.2, kH-69ppm, gH-35ppm
6) Twice weekly 40%
7) Aquaone plantglo sits 1.8 inch above tank
8) 8 red cherry shrimp, 4 salt and pepper cories, 12 neon tetras
9) I am going for an iwagumi aquascape and I would like a carepenting plant this is a nice green and will carpet most of my tank and doesn't attract algea to badly
Thanks
Seems like a decent setup.
So for lush green compact carpets:
Hemianthus callitrichoides
Micranthemum 'Monte Carlo'
glossostigma elatinoides
For a grass like carpet:
Eleocharis Parvula
Those are the most common you usually see, all lighter green in color. HC and monte carlo are more compact in growth with smaller leaves compared to glosso, I believe glosso is the easier of the three to get going. Dwarf hairgrass is also on the "easier" side or getting a carpet, but it could get a little tall and cover some of your hardscape in a smaller tank.
I would suggest cranking the CO2, this really helps drive these plants to carpet rather then grow upwards, but what your shrimp, they don't really like CO2 in my experience. Keep following the flourish schedule, perhaps look at estimative index dosing because you are already doing large water changes. I have great success with EI dosing.
I'll attach some pictures of HC (first pic), glosso (second pic -- note that the glosso carpet has not yet fully filled in) and dwarf hairgrass (3rd pic, also not completely filled in) for reference. I have not kept monte carlo, but it's on the bucket list. Google monte carlo carpet for pics.
Edit: sorry for the sideways images, darn Iphone pics
