| | Mr. Amano's approach at lighting (from AGA)
One thing that Amano mentioned at ADA seemed to strike a fancy with several people. It seams that he only uses really high light for only a small part of the lighting period.
For example: On the ~ 50g tank (90x45x45cm) that was demo'd at AGA, there was a fixture that had independend lights: 2x36 PC and 1x150 MH. Amano said that he would run the PC's about 10-12hours a day an only run the MH for 3-4 hours. I forget the whole explaination, but it had to do with supplying really high lighting only for a period of time that the plants would be able to fully utilize it.
Anyone use this sort of lighting cycle etc?
I was thinking of a 3x55 AH setup on a new tank that I am saving up for (24x16x16in). I would run a 1x55 10,000K 10-12hr a day and in the middle of the day turn on 2x55AH 9325K's for 4 hours. These lights of course would not sit directly on the tank, but would be around 10-12" above the tank. The outside reflectors would be angled inward to keep most of the light into the tank and out of the room.
