Hi CupidofCrime. I'll offer my 2 cents on a few things. Re: driftwood Keep in mind that driftwood can cause a yellowing of the water because of the tannins released. It depends. Eventually the tannins are depleted--I don't know how old your driftwood is. So it's something you might have to deal with. The tannins will also make your water slightly "softer" and slightly more acidic. Some fish thrive in that--discus and some cichlids, for example. And plenty of plants love that...like discus in a mangrove...but not necessarily a Japanese "look". Re: plant while the tank is cycling. I wouldn't. I would go very slowly and add things very slowly just like with a reef tank, which you're already familiar with. Re: 10K or 6700? 6700 or some of both. I recommend HO or VHO lights, and an open top unless you have jumpers (or a cat). Re: CO2 If you're going to dose, then dose during the day (lighted) phase and not at night or a smaller amount 24/7. For plants, there's one that I really liked called water lettuce or Pistia stratiotes. It floats on the water, the roots hang down, and it propagates readily. Little fish love it....but not necessarily Japanese looking. Definitely dip or quarantine plants before they go into your main tank. There are lots of ways to do that. I used to dip in a mild solution of KMnO4 for about 5 minutes. Rinse well, and Bob's your uncle. 2 last points. Keep in mind that you can have a very successful planted tank that is very low-tech. I'm a dinosaur, but I had a beautiful planted tank for 10 years (and a bunch of other tanks for breeding cichlids). I never once "tested" for anything in any of my tanks. I didn't even own a test kit. I never added CO2. I did invest in very good VHO lights. I changed about 15% of water 1X/week. Maybe you already know all this stuff. If not, I hope it's helpful.
