Allright, here are some pictures:

Did not upload any video. Quality is too low on my camera. It is obvious what is going on in the tank.
Added 30 neon tetras on Day4. As I expected algae appeared on the glass one day later (today). It's the brown kind and this has happened before in this tank when adding 30 other neons all of a sudden.
Pearling on Day 5 is like on Day 1, but only after a 30% water change. Before that there was pearling but not as much as on Day 1.
1. Plant leaf mass has increased immensely (3 new leaves on the big sword, 3 new leaves on the small sword, 6 new leaves on the lotuses, the second lotus bulb has a first new leaf)
2. Added Java Fern - as expected it pearls heavily
3. Najas sp. "Roraima" likes food in the water. It shows a slight pearling though.
4. There were some fluffy algae on the rocks even before I added the LED light. Grey like BBA but fluffly like diatoms. They pearled well on Day 1 as well as right now on Day 5 after the water change
5. Under the 10,000 Kelving LED the neons glow very intensely. Think of police officer's red and blue lights in the night - it's the same impression, except that here this is happening in a brighly lit tank.
6. On Day 4 I noticed a tiny amount of short hair algae showing up on some leaves. When I say tiny I mean like 15 hairs, very thin and noticeable only under a certain angle. You can see the same algae in some of ADA's tanks if there is a macro shot. The water in the tank had evaporated about 1/2 inch. The filter outlfow was stirring the surface pretty good and there was a nice underwater light shimmer too. But I gues the CO2 level had dropped. After one night (on Day 5) there was only a few hairs of that algae left. Darkness does not do it well and lack of food in the water is not good either. The 30 new fish apparently didn't help it either.
I don't think that at this point there is any doubt that this mix of a 30W 10,000 Kelving LED Flood light + a 24W T5HO Giesemann Midday is an excellent mix for growing plants. The question remains how long the intensity of the LED will stay good.
I will be posting an update once a week. And I foresee a very careful fertilizing of the water. The tank has inert gravel. The growth in the last 5 days has been nothing short of amazing because of that. This cannot go on without any food forever. As you all know I will be fertilizing at very low levels - so a test will not show anything but the food will be there.
