First welcome to the planted tank forum, and seeing you are hear you are headed in the right direction. This forum has people with a lot of knowledge and willing to help. It always helps to give has much info about your tank when asking question, also we love pictures no matter what you think they look like. We all started with an empty tank and expecting it to look like some of the tanks on this forum. (Dreams)
Second, coming from the reef side you should have some knowledge about cycling a tank and testing water parameters, itís no different with freshwater, just different test.
Third, driftwood comes in all different kinds and some will give off more tannins than others. You can always search the forum for more info on driftwood.
Forth, your reef light is most likely not the right spectrum for plants and may grow algae better, not what you want. But keep it on a short duration to start with and if you can lower the output percentage, I would do that also. Again there are people on this forum with better understanding of light than me, so keep reading.
Fifth, keep with low light plants at first, crypts and anubias. Your plants should be good, but you will need to start testing the water if you havenít already started, remember you need to cycle your tank before adding fish. I believe you can add snail also if the ammonia is very low. For shrimp I would wait a couple months and let the tank develop its bio-film for the shrimp to eat, I know waiting is hard, but it is better than killing shrimp. Also it is easier to start with an all in one fert for dosing, but start dosing less than what is recommended.
Just keep reading (I think I said that a couple times
) on this forum and learning as you go. The biggest thing that I have learned and read is patients. Roma wasnít built in a day. Enjoy the ride.
