Looks like Alternanthera reineckii to me. Close to Hygro but even closer to being Alternanthera.

Completely agree....

Just to name a few that you can check into....

Lobelia cardinalis 'dwarf'
Bacopa sp. 'Colorata'
Didiplis diandra
Hygrophila polysperma 'Rosanervig'
Limnophila aromatica
Ludwigia repens
Rotala macrandra
Rotala rotundifolia
Rotala sp. 'Colorata'
Rotala wallichii
Echinodorus bleheri 'compacta'
Hydrocotyle verticillata
Crypt Parva
Ammania senegalensis

Actually, anything above 2.5w/g should have CO2. If you don't, you are going to run into some algae issues, and the only way to eliminate it is CO2. BBA is a big one for that, loves low and fluctuating CO2 levels, and no CO2 as well. If the tank is ssmaller, then you can use Flourish Excel instead, as it's a carbon suppliment.

As for being careful with CO2, not really necessary IMO. I run my CO2 at 50ppm-78ppm regularly. The only time you need to be concerned is if it's running up around 100ppm and higher. Currently I'm running my 29G right around 50ppm.

Lastly, in very moderately to heavily planted tanks, you SHOULD run an air bubbler at night. Or anything that will give more surface aggitation. Plants produce O2 during the day, but take it in at night. I've lost fish due to suffocating, I woke up and half the fish dead and the other half gasping at the surface. Within 10 minutes after adding an airstone, all was normal and had to fish out the dead fish. And it included 5 Roseline sharks.

So, remember, plants PRODUCE O2 during the day, and USE O2 at night. The more plants you have, the more O2 that get's stripped from the water.

Actually, I don't recommend things like that for anything above 15G. You get above that tank size and you start getting CO2 fluctuations. Not a good thing, unless you run more than one together.

For the 29G, I would just purchase Flourish Excel. It's much easier, and you don't have to worry about fluctuations, and then run an airstone or other surface aggitation to help keeo O2 and CO2 at ambient levels. I personally like just using a small powerhead at the surface pointed slightly up to give surface aggitation, rather than an airstone. Plus it circulates the gases when they enter the water.

Lastly, there are a couple of plants to stay away from if you do use Excel, and they are anacharis and vals. The Excel will make them melt. Other than that, no other problems....

Edit:
For the 65W CF, with it being more intense than a regular 65W florescent, it's about 2.9w/g. I guage CF as approx. 1.3x the regular florescent, so 65x1.3/29=2.9, approx.
