In a moment of panic and completely impulsiveness, I flooded the tank and planted it tonight. When I got home today the yogurt had developed a lot of white spiky mold. I even noticed a little on the substrate near the lower mossy areas. After tomorrow, I'll be away from my tank for 4 days, so I got super nervous that mold could take over the tank and kill all of my work.
I grabbed one of my test pieces of wood and ran it under the faucet. To my surprise, the mold was hanging on. Long term? Who knows? I am comfortable leaving it for 4 days with CO2 and a filter, so I figured what the heck, lets go for it.
I slowly flooded the tank, and only a little bit of the moss has lifted. Most of it is stahing put so far. All of the UG stayed happily planted. This is not 100% of my plants, but it's most of them other than a bunch of rotola. It's possible that I'll come home and the rest of the moss will be floating around the tank, but I really hope not.
I apologize ahead of time for the darkness of the pics. I'm tired, so I just grabbed the camera and took the shots, not realizing I had it set to under expose by a bit for an earlier shot. The water is also a bit cloudy.
I'll post better pics later. I'm off to bed.
Here is how I planted the tank:
