Things went well. I chose giant hygro to grow emersed and boy did it. Actually, it outgrew my tank. About 3-4 weeks into the 1/3 level drop, the giant hygro was well above the tank, almost 6"!! The root mass was overwhelming to the point that I could not see the back of the tank on the left half of the tank and there was no signs of slow down.
At week 5 the sunset hygro started to look sick and the old submersed giant hygro leaves were looking poor. I had 0 nitrates, 0 nitrites, unmeasurable iron, and just about anything else. The hygro had sucked all the nutrients out of the water column.
I spoke with the LFS plant guru who suggested adding 1ml/day of Flourish, increasing by 1ml/day every 3rd day. I was to do this untill algae growth, stop for 3 days and continue a the level prior to the algae growth every other day. I was up to 5ml/day and still no algae growth!!
Work has been insane the past 2 weeks and yesterday I was really able to look at the tank and the Giant Hygro was beautiful. The sunset was amazing red with no Co2 and moderate light.
I hated to take the Giant Hygro out, but when I attempted to trim (If you can call cutting stems the size of your pinky finger trimming) I soon realized the plants had grown so intertwined, there was no thining them out without a major hack job. The nice thing is that the sunset hygro had grown so much, I was able to trim enough to fill in most of the other side of the tank.
Thanks for the information. Now I know why the LFS guy stated that the giant hygro was the weed of the aquatic world.
