Your FW tank has come a long way.

If you are going to get involved in FW planted aquariums, I highly recommend the book Encyclopedia of Aquarium Plants by Peter Hiscock.

You'll find that this area can be almost as complex as a reef system.

I point this out because it looks like you have several species of plants that are often sold as "aquarium plants" but are actually house plants, and they do not do well long term. You also seem to have several species that are very demanding in their light requirements. The typical aquarium reflector, even with a decent bulb, is just not going to produce enough light.
